Is there any rabbinic literature explaining why Hashem created only one planet (Earth) in the whole entire universe that can support intelligent life?

    How do you even know this claim is true? There is almost certainly another planet somewhere that can support life.

Technically, given the way the Torah deals with life on Earth, there could be worlds designed for future settlement or worlds with intelligent beings and travel possible or impossible. Note how the Torah ignores the other civilizations on this Earth except as they interact with Bnai Yisrael. You should be asking if Chazal deal with the possibilities of other worlds.

For example Is There Life on Other Planets?

Several Torah scholars of past generations have discussed the possibility of life on other planets. Rabbi Chasdai Crescas (Spain, 1340–1411) wrote that there is nothing anywhere in Torah that negates such a possibility.3 Rabbi Yosef Albo (Spain, 1380–1444), on the other hand, disagreed.4 Rabbi Pinchas Horowitz (Poland 1765-1861), cites Albo, but rejects his thesis.5

  1. Ohr Hashem 4:5.
  2. Sefer Ha'Ikrim.
  3. Sefer HaBrit HaShalem 1:3, 4.

There are discussions as to whether beings on other planets would or would not have free will and what Hashem would command them and would they be given a (or the) Torah. Since we cannot determine this, any discussion is a matter of opinion based on how we read the Torah.


I would bring Zohar Teruma (ח"ב קסא, א):

דכד ברא קוב"ה עלמא אסתכל בה באורייתא וברא עלמא

G-d looked at the Torah and created the world accordingly.

As the Torah does not mention the creation of other intelligent creatures we can interact with, besides animals and other humans, we can conclude G-d didn't create alien worlds we can interact with.

    The Torah doesn't explicitly mention phones, cars, or hataras nedarim. I guess none of those exist.

  • @Heshy 1. Torah doesn't mention OUR creations of course, like AI, agreed. 2. I said "I would" to point to a possible explanation, I didn't judge its veracity. 3. as we discover more and more things not covered by our Halacha (think electricity) we start seriously doubt the extent of our Sages' and Torah's credibility (I personally think the technological revolution caused secularisation exactly because of this fact). I hope we will not bump into aliens, because the first question I'd ask is "what Torah do you guys have and how did you get it?"

  • What's the difference between if we contacted aliens tomorrow and when we contacted Native Americans in 1492?

  • @Heshy Native Americans (or Chines or even Australians) fit perfectly into our Torah - they all are Adam's descendants. But where do the aliens come from? The flood? G-d created Adam, so the Torah says, and no other intelligent (Neshomah-bearing) creatures.

    Where does the Torah say G-d created "no other intelligent (Neshomah-bearing) creatures"?
