Is There Life on Other Planets?

Is There Life on Other Planets?

The Jewish view on UFOs, aliens and extraterrestrial intelligence



Someone told me that according to Judaism, human beings are the only conscious beings in the universe. Is there any basis to this?


Certainly not!

First of all, the sages discuss the fact that animals also feel pain, based on the biblical prohibition against causing them undue suffering.

Second, there are plenty of accounts in the Torah of the higher angels, who are conscious of a realm of reality far beyond ours.

Third, Maimonides and others write about the heavenly bodies as conscious beings—and not simply in an allegorical sense. If anyone should ask, “How can a ball of helium and hydrogen contain consciousness?” simply ask in return, “And that a warm mass of gray meat has consciousness is reasonable?”

The uniqueness of humankind is not our consciousness, but the way that consciousness is able to enter the realms of good and evil, make decisions and distinguish between them.

Sources in Torah

The Lubavitcher Rebbe pointed out that there is support in Torah for the notion that life exists on other planets. Furthermore, we can know something about that life through deduction from what the Torah tells us. Here is his argument:

In the Book of Judges (5:23), Deborah the prophetess sings about the victory of Barak over Sisera. In her song, she says, “Cursed be Meroz! Cursed, cursed be its inhabitants, says the angel of G‑d!”

Where is Meroz, and who are its inhabitants? The Talmud gives two explanations, one of them being that Meroz is a star or planet. The heavenly bodies had also come to help the Israelites, as Deborah stated just one verse earlier, “From the heavens they fought, the stars from their orbits . . .” This star, however, which was the dominant star of Sisera, apparently did not come to their aid. And so, General Barak penalized Meroz—and its inhabitants.

Are these inhabitants intelligent? Intelligence is defined by Torah to mean the capacity to make decisions with free will. Free will is only possible where there is Torah, whereby the Creator offers His creatures more than one possibility and asks that they make the appropriate choice.

So, if there would be intelligent life elsewhere in the universe, those creatures would have to have Torah. Could they have a different Torah than us? This is not possible, since Torah is truth, and there cannot be two truths.

Could they then have the same Torah as us? This also seems impossible, since the Torah itself describes in detail how the Torah was revealed on this planet, and that account itself has a strong impact on how the Torah is to be fulfilled.

It therefore appears that although it is quite possible there is life on other planets, that life would not be intelligent in a way similar to human life and culture.

But should we be looking?

Dr. Velvl Greene was a biologist who was enlisted by NASA in their project to determine if there is life on Mars. He asked the Lubavitcher Rebbe privately if this was something he should be doing.

The Rebbe replied, “Dr. Greene, look for life on Mars! And if you don’t find it there, look somewhere else in the universe for it. Because for you to sit here and say there is no life outside of planet Earth is to put limitations on the Creator, and that is not something any of His creatures can do!”

An finite cannot an infinite.
And vice versa. No one has produced anything that is infinite. All are reluctant to consider a finite universe - not realizing an infinite negates science as nothing else can.

Let's be boldly honest; let's not be swayed by ancient sounding text and read its actual import for today's science. Imagine we have to say something scientific to a people 3,000 years ago, without infringing their knowledge vocab: how would you say it for all generation's understanding - a literary feat in itself?

The Hebrew Bible gave us the first recording that introduced the finite premise: 'In the beginning God' = Once the universe never existed; 100% finite.

And that the Earth is billions of years old: count how long for the separation of land and water, mentioned before the advent of life.

And the only true definition of both finite & infinite being that of change. Anything subject to change is finite; we know of nothing that is not subject to change:
"I am the Lord I have not changed.'

Finite and infinite
Yep, some things are infinite and some are finite. What's the problem? I see none. That an infinite universe now exists where none existed before is not a problem for me either. That's the reality we are living in, an infinite universe filled with an infinite variety of life, all created by HaShem in His Infinite Wisdom. Enjoy !!!

Are so many aghast of considering a finite universe? It appears anathema even as a hypothetical premise. If its one of only two possibilities and we are not certain which - should it not be on the table? The scientific fact is that a finite Uni is not an un-scientific premise; it fully aligns with 'cause & effect'. So why not try it sometime and see how it fits reality; only then can a reasonable discussion become legitimate.

An infinite universe needs no science. Everything was always there.
If stars were not always existing it means once light was not existing. By sub-sequence, all components once never existed. The devised age of the universe with the Hubble discovery of an expanding universe, says once the universe never existed.

Were meroz was located and which creatures were there

Can there not be a different truth for a different world?

Setting the record straight.
There is no proof the universe is infinite. There are only 'indicatives' that negates infinite and inclines with finite. However, it is incumbent from a science view, that both scenarios should be considered, and the finite one should never be disregarded or ridiculed.

Those who hold an infinite view should also state what applies if the uni is finite, describe what they mean by absolutely infinite and absolutely finite, even if this is hypothetical to them. Otherwise they are not considering one of only two possible outcomes and subscribing to an un-scientific process of discourse.

Anything new?
Yes, science is always pushing "science fiction" into the realm of a "new reality". What was impossible for most people to even imagine 100 years ago, is now our current reality, AND, it will continue on like that. Enjoy ! The universe is infinite; there is no end that the human mind can comprehend.

Why we do not add or subtract from the Hebrew Bible.
The opening 4 words say "In the beginning God.." It means at one time nothing existed accept God - with no additives applying. It also means the universe is finite with a beginning. This is very logical and anything else only pushes the goal post further to face the same brick wall.

Analyze this!
Every atheist scientist miss-quotes Genesis by omitting that according to Genesis the universe is 100% finite. Genesis says 'In the beginning God' - this means once nothing but God existed, not even darkness, space, or time existed. This negates parallel Uni's, MV, string, etc, etc. because they violate the finite premise and merely push the goal post further.

The underlying reason for omitting the opening 4 words of Genesis is that it scientifically & mathematically reasons, by the process of elimination, the universe had to have a universe maker. QED.

Pls name an alternative premise for the universe emerging based on a finite one. Anyone.
