“Chesed L’Avraham” (the grandfather of the Chida) speaks about what the Zohar discusses about there being seven hidden lands, with various beings living in each land. The Zohar speaks of the inhabitants of one of the lands called “Neshaya”, where the people are shorter than our people. The Chesed L’Avraham says that the world is essentially hollow, with various layers, like the layers of an onion, and he describes the inhabitants of “Neshaya” as having large heads, small bodies, no ears or noses, only holes, and a small slit for a mouth, and large black eyes. He says that these people do take people sometimes briefly for their needs. Sounds like “grey aliens”. Probably what people think are the aliens from other planets are actually the people from Neshaya under the earth. It is still possible though that there is life on other planets, but those who abduct people are probably closer to us than other planets.
The Me’am Loez on Parshes Berashis (Daf Nun or Nun Aleph) talks about Aliens. He writes that there are aliens with a human head and horse body; like a Centaurs. He also writes there are planets where there are very handsome people, but they cannot grow food. They come to this world to eat people! Speaking of Alien Abduction!
