How Old is the Universe According to Judaism?

How Old is the Universe According to Judaism?

The Jewish View on the Age Old Question


The Short Answer

We can't tell how old the universe is by examining it, because we don't understand how it got here in the first place.

A Longer Answer

If you met someone on the street and wanted to determine how old this person is, you would have one of two options. You could examine circumstantial evidence. Or you could ask this person, "Excuse me, how old are you?"

Let's start with the first method and do this systematically. We have overwhelming evidence that the universe is currently expanding. All we have to do is measure how fast it is currently expanding, its size, and its total mass, and we can work backwards to when it must have started. The result? The current estimate is fifteen billion years.

Piece of cake, right? Well, not quite. You see, we're missing an important step—the very first one. We've traced our universe back to the starting line, as a single glob about to explode. But what made it explode? How did it get there? What came before?

So now we're left with the job of tracing something back to nothing. That's not so simple. If we want to be thorough, we will need to reconstruct various degrees of nothingness and somethingness in between, and describe how one evolved into the other. All these are things our scientific instruments cannot measure—science deals only with things that are something. Science is lost when discussing something before it became something. To get technical, science can discuss temporal causalities, but not ontological ones. Which means that if you're going to direct the question, "How did our universe come to be?" to a scientist, you might as well direct it to an accountant, an artist or a real estate agent.

The Kabbalists, on the other hand, dealt with just that: A hierarchy of being, starting with an Ultimate Source which transcends the whole system of being and not-being, and working down through a systematic, interlinked chain (evolution) of multiple universes that terminate at our rock bottom, physical world. But none of this is within the domain of the physical sciences, which rely on precise measurements of phenomena or their effects.

On the contrary, as the Lubavitcher Rebbe wrote to Rabbi Dr. Herzog in 19561 (the following is my own free translation from the Hebrew): "According to the conclusions of contemporary science, the annihilation of anything—to return to nothing, or the opposite, creation of something from nothing—are impossibilities within the natural law.

"And further, creation ex nihilo, from a scientific perspective, is more implausible than having a human being appear out of the inanimate mud, just as he is, with no stages in between."

Now we've thrown a wrench in the works. How can science tell how long the world has been around, when it can't describe—or even allow the possibility of description of—the processes by which the world came to be in the first place?

Cosmic Birth

To give an analogy, let's say I examine an alien to determine his/her/its age. I announce to this friendly and cooperative being that by my calculations, he/she/it was born 108 years ago. To which he/she/it responds, "Who says I was born?"

Good point. Maybe our friendly alien gradually took form, passing through a period when it was neither alive nor inanimate. If so, how do we determine the point to begin counting its age? Or perhaps it existed initially as an ethereal being and only yesterday materialized as a fully adult alien.

If you think this puts you at a disadvantage, imagine if we would turn the tables and ask the alien to age us. He may perform a thorough examination of us and our environs and determine that, given the cosmological forces of which his civilization is aware, and given the chemical and energy makeup of our planet, for such a complex bio-system to develop out of the earth would take about 2.5 million years. To which we respond that we humans are actually born with limbs and organs already in place.

Don't be surprised if he flatly rejects such a notion as absurd. Even an earthling, Maimonides, gave 43 reasons why live birth is rationally impossible. If you've ever been in a delivery room, you'll know what he's talking about: In a moment, a new, complete person appears on planet earth. It just doesn't look, well, normal.

Yet, within our biosphere, birth is the standard form of origin. Things tend to arrive on the scene fully assembled. The alien may not have known about this. But the human being has no excuse for failing to integrate this phenomenon into his intuition. Instead, we insist on speculations that over-simplify the cosmos into neat, gradual evolutionary patterns on a single, horizontal plane of existence.

Which is just what we are doing here: When we wind back time to the origin of the universe as a single glob and only then ask the question, "Now how did that get there?" we are arbitrarily breaking a single answer into two steps. We're saying, First it came into being. Then it evolved to its present state. But maybe that's not so. Maybe both processes occurred at once. Perhaps the process was shared over multiple states of being, wherein processes occurred at varying rates?

A simple analogy from geometry: Draw a square. Now make a path from the top right corner of that square to the bottom left corner. Did you first travel to the bottom right, and then over to the left? Or did you make a diagonal straight to your target?

Figure 1: Time & State of Being—choose your path

So, too, here, there are two co-ordinates:

a) The process that led to the design and form of our cosmos.

b) The ontological transition from nothing to something.

Perhaps they occurred simultaneously, in tandem. Or maybe they didn't. That's just the point: We have no way of knowing.

But the answer is crucial to our quest, because there is another unknown: How does time behave in a higher state of being? When form and substance are more loosely defined—as they would be in a pre-material state—can cause and effect occur over a shorter period of time? In truth, is there any sense in talking about time at all at these stages?

G‑d's Womb

Before you get the feeling that we are completely lost, let me point out that in truth, we do have some frame of reference. In the form by which G‑d created heaven and earth—the macrocosm, so He made Adam—the microcosm. The human being includes processes that match every level of the ontological hierarchy mentioned above. We don't just perform material tasks, we talk about them, we think about them, we have feelings about them, we conceive what those tasks will be somewhere in our consciousness or pre-consciousness, and—even before any of this—we begin with a simple desire for something to be. So, by examining those processes within the microcosm of our own psyche, we can get a picture of how all this works in the grand macrocosm.

And lo and behold, a discovery awaits us: The higher we go up the hierarchy, the more rapidly those processes occur. What takes years to perform may take only hours to describe, minutes to dream about, and a flash of a lightning bolt to desire and conceive.

If the cosmos was conceived and incubated in the womb of G‑d's mind, at which stage was it born into the time continuum that we measure with our physical senses? Is it conceivable that geological, chemical and organic processes that would take billions of years in our realm could occur within the equivalent of hours or minutes or even nanoseconds—or perhaps zero time—when occurring at a higher state of being but counted from our realm?

Take the oceans, for example. The account in Genesis begins discussing the Creator's conception of a single ocean and concludes with His actual creation of multiple oceans. Could continental drift have occurred within the gestation period between conception and birth—thereby breaking the great ocean apart? If so, many questions would be answered: Continental drift requires huge expenditures of energy that should melt the earth in a short time.2 Perhaps in a higher ontological realm the process could occur non-destructively, as well as much faster.

How about the origin of life? The Ramban (Nachmanides, 14th century Jewish scholar) understands Genesis as saying that the water, through its movement, metamorphosed into the creatures of the sea. This, then, is a description of a kind of evolutionary process. It's not just G‑d says fish and fish are there. G‑d directs a natural element to become fish, just as He directs the earth to sprout forth vegetation. But it occurs rapidly and with deliberate direction. The origin of life from inanimate chemicals remains an elusive puzzle for biologists—it is statistically impossible for it to have occurred by chance. Could this synthesis have occurred, as we said, in the womb of G‑d's creative mind, at a higher plane of being?

Interestingly, the Kabbalah also describes an incremental process of formation—albeit in terms far beyond the crude mechanics of materialistic evolutionism. Rather than physical organisms transmuting into increasingly complex forms, the ancient Book of Formation describes the letters that form the words of the account of Creation passing through an (almost?) endless series of permutations to recombine and generate all the details of every instance of the cosmos.

The process has been compared to the workings of the human mind: The mind begins with a simple seed of an idea. Then, in gradual stages, it generates vast sets of corollaries, analogies and applications, each with its particular set of words by which the mind articulates these ideas to itself and to others. Certainly, this paradigm provides a coherent alternative to Darwinism to explain the apparent phylogeny of the species.

Once upon a time, scientists assumed they had the keys to absolute knowledge. The last hundred and fifty years has brought us to acknowledge there is no such thing within the realm of standard human perception and reason. When it comes to facts alive and well in the real world, we can make some pretty good stabs at the truth. When it comes to questions of the future, we can make limited speculations. When it comes to knowing the origin of things, empirical materialism is completely out of its realm. Perhaps we are ready today to recognize a place for the inner vision of the prophet and the mystic.

The Alternative Answer

As we said before, there is another method of determining age other than hypothesis and speculation. If the subject is a conscious being, we can ask him/her/it, "Excuse me, do you have a memory of how old you are?"

In the case of the cosmos, we have asked. Of course, some will call it speculation, or even "primitive imagination." But then, I wonder what scientists a century from now will call the speculations of today's cosmologists? As for me, my understanding of the Torah is that it is not a human voice, but the voice of the essence of the cosmos itself.

So we asked.

The answer at the dating of this writing is 5,761 years.3


To be truthful, the Rebbe's uncompromising rejection of any marriage of Darwinism and Genesis often puzzled me. So many theologians have been quite eager and willing to reinterpret a few lines of the Torah to make room for the scientists, whereas the scientific community is almost universally intolerant of those who step outside the Darwinian catechism. It would have been so much more convenient for the Rebbe to concede to the scientists and thereby please both sides. But then I read an essay of a significant American scientist, Prof. Wolfgang Smith (Cosmos, Bios, Theos , pg. 115, ed. Margenau and Varghese, Open Court, Chicago, 1992). The entire essay is worth reading (as is the book), and I admit to having borrowed some of his terminology in this essay. To quote one succinct paragraph:

At bottom, evolutionism is the denial of transcendence, the desperate attempt to understand life on the horizontal plane of it manifestations. Religion, on the other hand, is perforce concerned with transcendence and the vertical dimension, in which alone the re-ligare or binding back can be effected. The supposed merger, therefore, of these opposed doctrines constitutes one of the most bizarre happenings in these already confused and confusing times.


The entire letter is well worth reading and is published in Ma Rabbu Maasecha page 262, and in Igrot Kodesh, vol. 13, pg. 143.

This age is according to ancient Jewish tradition, and can be calculated by compiling the chronologies written in the Torah.

Evolution With a 5000 year civilization the best Egypt could come up with is a pyramid, a great achievement for its time. How does that compare with a modern skyscraper?

There is no mention in the Bible of the world being round.

There is no mention in the Bible about a rocket going to the moon.

There is no mention of a telegraph, fax machine, cell phone, TV, etc., in the Bible.

Why? Because the human brain in those times could not even imagine those things. It took years of evolution to develop the human brain to a higher level. Reply

Q: What is the first products of the Universe? the earth, which was without form and void, and darkness was on the face of the deep.

What is Truth, Evolution or one of the religions? Truth: did the Bible come by men or God. Does the Bible hold up on prophecy, on health science (diet & Cleanliness laws), on consistent teaching & history? Yes!
Evolution does not look at all of the possibilities - it denies anything divine. If it does not understand it adds a few million years Kiss a frog & get a prince is a fairy tale, but given millions of years & frogs change to princes.
Then we have timing mechanisms to "prove" the extended times. They admit they do not know the state of the time markers "in the beginning" but still extrapolate their timing. Other timings are upset by water, yet they use them to date fossils & sedimentary layers -all needing water to happen.
Prove your faith, hold fast to Truth. Do not have a belief system based on your parents books or idols, or old rabbis, but look to what changed Abraham from an Iraqi to a true Jew even before his grandson Judah from which they are named. Jewishness is of the heart & head.

vertical vs horizontal dimensions Sometimes, using analogies are cute, but they are just ways of coloring ideas. Don't we live in three dimensional space? Who defines what is vertical and what is horizontal? Some think the opposite, that religion is one dimensional and science is three dimensional. Nothing can change with religion. Yet, evolution is constantly happening and changing. Religion is static. Evolution is change. Religion is faith. Evolution is observation. Religion relies on what a "holy book" says, and which holy book do we use as the true reference? Whcih one is right, and by choosing the right one, you must negate all other religions, since they say different ideas! So, which religion is right, and then say the other religions are wrong, and be strong enough to stand up when they attack you for descriminating and slandering their religion. How can there be more than one correct religion ? Is sat or Sun the holy day? pary facing east or west. pray 3 x a day or 7x? eat pork or not? which? Reply

Anything subject to change is finite. The Hebrew definition for infinite is evidenced by change, namely, "I the Lord do not change" [Isa]. I find that description the best, un-challengable and 100% accurate measure of both finite and infinite.
It means, anything subject to change is finite. There is nothing in the universe that is not subject to change. Inversely, it means anything not subject to change on any level, is infinite. It means also that evolution, which is ever changing like all things, is not an infinite process.
This process never existed at one time, perhaps as in in V2 of Genesis, and it began perhaps in V3, which records the first command action to create Light ["Let their be light"].
Evolution did not create darkness or light, because then nothing else existed that could interact and form darkness and light; there was yet no energy, explosions, photons or other particles. Reply

other religions and their belief of the Earths age That is what science aims to get rid of. Use every possible piece of eventide to come up with a hypothesis, a guess, then do tests and research to find out a outcome, rinse and repeat until a theory, or answer, is developed. This is how we (in basic terms) found out the age of the Earth, witch is about 4.2 billion years old. Reply

'steve' Steve, you are correct. As fact, because there are so many different religions on offer, it necessarily makes all of us an atheist with respect to other religions. Which religion is the correct one? The majority? The oldest? Science is purely objective, there is only one science and it has no association with any type of faith. It relies on evidential support. Science is NOT a religion. Reply

a simple analogy Here is a simple analogy. 100 people look at an object and are asked to say what color it is. 10 say it is red, 10 say it is blue, 10 say it is green, 10 say it is yellow, 10 say it is white. The are 50 people remaining. These 50 have the opinions of the first 50 to consider, and there are 5 groups of 10, each sure that their belief is the correct color. Does the belief of the first 50 influence the beliefs of the last 50, who have not yet expressed theirs? So, if you were in the last 50, do you evaluate each of the 5 groups beliefs and then chose the one you feel is most likely? Or, do you go to the object itself and look to see IF you can determine it’s color by examination. Is it possible to come up with a set of criteria to use to get a better idea of what the color is? Or, should you examine the 5 different belief systems and go by the belief system you feel better with? Do you go by one of the belief systems that says, the color of the object is determined by what a holy book my parents gave me and I cannot disagree with what this holy book says, even if it disagrees with the criteria you picked to objectively examine the color of the object.
To summarize, it is impossible to argue a point, when your belief is based on a book that your parents gave to you, that cannot be contradicted even if it disagrees with what you see. Reply

My problem with the evolution theory. It is given as an 'on-going' process. Therefore it should manifest itself continuously without pause. One must start a second after the last one, all over the region. This says we do not have to wait for millions of years to see this in action. And we don't.

The other problematic issue is that of survival of the fittest. If life prevails on earth, even in harsh volcanoes, why has life not occurred by adapting in other harsh planets. Is survival of the fittest exclusive and limited to only one kind of harsh environment?

Such issues make the ToE unlike science, where 2+2 = 4 in all places of the universe. Reply

It wouldn't surprise me if we started to see, in the next centuies, subtle shifts in the phenotype of creatures displaced by climate change from the present biomes. Reply

other religions and their belief of the Earths age Can you simply discount that there are many other religions, some that do not use our Bible as their holy book, and these have a different account of the age of the universe and of creation itself? Can Earth be 5000-6000 years old for the Jewish people and a different age for others not Jewish. The answer, if you base your thought on faith, is that the Earth has different ages. Would you look at someone who believes in another religion and tell him, "even though you have faith in your holy book, it is incorrect because our faith in our holy book is more important!" You see, the basic, founding principle that something can be holy for one person and not for another is the problem, it is the root of evil, and the cause of hatred and discord, and leads to disagreements based on "this is my faith, how dare you question its truth". This is the basis of evil, and the loss of free will. Reply

You say, "The earth is roughly 6,500 to 7,000 years old and there is much proof of this."
What is the 'much proof' you are referring to?
You say, "Evolution is a religion!"
How do you arrive to this conclusion that, Evolution equals religion? Religion is faith based. Evolution is scientifically based.
Where do the evolutionists claim that dogs have produced non-dogs?

Joseph Shellim Sydney November 25, 2014

"The earth is roughly 6,500 to 7,000 years old and there is much proof of this. Evolution is a religion! " Genesis lists numerous actions occurring on earth prior to the introduction of life. These actions can account for billions of years. Count how many time-factored years for the separation of light from darkness [for the universe age], and of water from land [for the earth's age].
Secondly, how does one account for a book that introduces the DAY and WEEK, introduces the premise of species in their correct protocol, yet does not account 'hours' - which would otherwise be a simple matter to measure if the vegetation appeared in a 24-hour day - or one that can be millions of years in its formation. It seems illogical that a source that can produce the most judiciary accepted laws of any other writing, and list genealogies with great mathematical accuracy, would make such a naive typo. Reply

creation In the beginning G-D created the heavens and the earth.....
In that moment, G-D created time, space and matter....
The earth is roughly 6,500 to 7,000 years old and there is much proof of this.
Evolution is a religion!
In order to prove evolution, you must first prove the following.
Cosmic evolution: the origin of time, space, and matter from nothing in the “big bang”
Chemical evolution: all elements “evolved” from hydrogen
Stellar evolution: stars and planets formed from gas clouds
Organic evolution: life begins from inanimate matter
Macro-evolution: animals and plants change from one type into another
Micro-evolution: variations form within the “kind”

The first 5 are purely religious.They have NEVER been observed.
The last one happens, we do get variations within the kinds.
A dog has never produced a non-dog....that we have ever observed.

Re. life can function without the need for a supreme being to intervene. From a science view, there are no alternatives to a Uni maker - if based on a finite universe: name one? Here, we eventually will arrive to a first particle with no internal or external products yet emerging; no space, energy or time or nothing contained in this universe - else the finite factor becomes violated. In such a scenario no action can be produced because no interaction of two particles is possible.
Genesis is based on an absolutely finite premise ['In the beginning God'].

Evolution is a program factored in the creation code same as the rain cycle. Genesis is scientifically correct when listing pre-life anticipatory actions such as separations of light & darkness, water & land, and that life was activated after the life cycle began. Evolution cannot happen without a program allowing it to do so. It is specific to Earth: we do not see survival of the fittest on other planet's harsh conditions, while we see life on earth's harsh conditions, even in the core of volcanoes. Why? Reply

No requirement to follow laws before formally revealed. The Oral law was made while in the desert and the people stood in lines asking explanations from Moses.

lack of sophistication Sigh... it is a shame to see how myopic the world has become.

The problem is that such chains inhibit the imaginative perception that gives rich hints as to the fallacies inherent in "accepted knowledge". Reply
