A young biologist was working at NASA on a project to find life on Mars. He asked the Rebbe, “Is this okay? Some religions say we shouldn’t search. After all, the Bible doesn’t say anything about life on Mars.”

The Rebbe replied, “Professor Greene, you should look for life on Mars. And if you don’t find it there, you should look elsewhere. Because for you to sit here and say that G‑d didn’t create life elsewhere is to put limits on G‑d, and no one can do that.”
