Fact from fiction, truth from diction, you look at it from a scientific logic perspective and nothing further you can’t deny it; even with no smoking gun the logic speaks volumes. If the mankind got its start here eons ago because the primordial soup with the right enzymes was zapped by a lightning bolt in a thunder storm spawning life it had to have happened elsewhere. To say we are not alone would be statistically impossible. It would be like someone winning the Powerball Lottery and having it roll over and over in perpetuity without ever having another winner.
Having had this jackpot happen else where out there I can see them visiting but not making contact; we are too barbaric, it would make about as much since as man going into the territory of some very aggressive and dangerous wild beast and trying to make friends with it. Life elsewhere quite plausibly happened 100s of millions of years before Earth leaving us to be like Neanderthal man in relation to today’s society. To Neanderthal we would seem like Gods, the things we can do with our technology they could not fathom, even those of the Dark Ages would be quite amazed and maybe try to burn us at the stake for being witches.
Abductions are also plausible, when man goes into the wild what do we do of those we don’t kill for pelts or eat? We go out and trap some, tag some, let them go to track where they travel. To a race or species from ”out there” we would be no better than a wild goose next to them. People want to dismiss that because the thought that Earthly man is not the cock of the walk in the Universe un-nerves people.
If I were them knowing what I know of man I would keep my distance the same as I would keep it from a swarming hornet’s nest.
