I can’t believe this hasn’t been raised yet. The notion of intelligent life contradicts the ideas of Hashem not creating something for no reason, the fact that zos hatorah lo segay muchlefes and that there will not be another Torah from Hashem.
There’s only one Torah, which was given here.
So what purpose would that intelligent life have? How would it fulfill the purpose of creation(to bestow upon creations olam haba) if they cannot have mitzvos, and have no way of figuring out the 7 mitzvos (since they’re not bnei noach)
Aliens appeal to a non earth-centrkc worldview, which ascribes no special value to humanity over anything else, and that life happened by chance cv”s. If it could “happen” here, it can happen there too.
Hashem created life for very defined reasons. There’s no secret of the cosmos that we’ll figure out empirically through discovery and space travel. Everything we need to know is in the Torah, and there it says the purpose of creation.
Beings with bechirah would have been created for nought, as there’s no torah anywhere else.
Animals and non-bechira individuals are definitely possible, as Hashem might want us to have resources (especially if there’s vegetables etc) or refuos, etc..
