I dont understand how Hashems providence is proof of extraterrestrials. Hashem is called HaMakom- He is everywhere and was metzamtzem Himself so to speak so this world can be created in the space. Hashem knows everything, sees everything. What does flying through 18,000 worlds mean? Isnt He everywhere at all times?
Also what would be the point of extraterrestrials if they have no free choice? Didnt it say Hashem created the world for Yisrael? And didnt he create it so we can choose right and come closer to Him? Extraterrestrials wouldnt have that.
Is it kefira to say there are other worlds with different purposes?
Maybe these places are for neshamos that need to get punished, but dont want to make any more mistakes, so Hashem lets them go to one of these worlds so they can get cleansed.
Just a hypothesis.
Or maybe these places are in a whole different dimension.
After 120 do our neshamos still exist in space as we know it? That was something i was always curious about.
