I still think it is "us, of the future" time traveling, even if we think it can't be done, maybe we figure it out later down the road? ....these drawings on rocks of spacecraft and people in space suits are human...they look like us..... what are the true odds of that, if they came from millions of light years away, that they would have evolved in the same manner and ended up looking like humans??
Even the grays that people seem to think they see....they are little, have eyes arms legs, they are just smaller with bigger eyes....and radiation from a major nuking could have sent us underground which made them develop larger eyes that can see in the dark, and they are grey and smaller due to radiation or lack of sunshine, stunting our growth!
like I said, I just love Sci fi stuff....
Time travel intrigues me more than aliens tbh.
