Wiki has a pretty good overview of the animal stuff. The organs and tissue removed are very selective and done with cuts that rival a surgeon.
If they are here, they had to get here at faster than light speeds and/or sum kind of dimension control… Which to me implies that an entity can step outside this reality/space-time. Again huge(?) regarding the possibility of an afterlife. Being able to manipulat space/time would damn near make you immortal?
So if they are hanging around here with this super advance technology and have been doing so for who knows how long (why not 4 thousand years?),,, if follows that they must be in some sense our masters/designers/overlords as it is certain that it is well withing their capabilities to throw a few asteroids at us and destroy us if they wanted to… They haven’t taken control of us overtly… Certainly they may have some kind of “hands off” star trek policy..
For now I’ll make the contention that they are stealing our culture (ZZ Top mostly). In a like manner it could also be that the “afterlife” is also stealing our culture because we are a font of creativity…
I think it is immoral for the space aliens not to help us?
I think it might be possible too that we might be just a few scientific breakthroughs away from knowing as much as they do… Rather than the universe being super sophisticated might not there be a ‘fractal’ dimension that, once figured out,, provides most of what’s needed to understand reality? Fractals are very cool.. Something akin to what Dawkins is saying,,, It would be more likely that the universe is simple in construction than complicated,,, especially for it to get started at all… Simple is relative,,, but the very first life forms developing from primordeal soup were pretty complex,,, but things start simple and become complexer,,, includeing the universe.
Fun stuff to think about…
