We literally just don't have sufficient information to make a most approximate educated guess, with a sample size of one.

The effort needed to fabricate all the evidence to the contrary would be far too ridiculous for consideration.

The fossil record alone would require a borderline omnipotent entity to fake. And yeah, there are some ever shrinking gaps in it but trying to fit the entire "humans are actually from Mars" theory in it is beyond absurd.

And then you have the mitochondrial DNA and other factors which allowed us to map the Tree of Life of all known organism, a model thwt we fit into quite well.

Water is incredibly good at radiation shielding though, and even though ice is slightly worse, it's still great for it. And we're talking potentially dozens of miles of ice here.

Hmm, unless it was also tidally locked maybe?

Exacrly. It's fucking clickbait of the lowest order, meant to elicit fear and nothing more.

This is the equivalent of saying "There's a gun aimed at you!", while the gun in question is being wielded by some dude in Caracas, Venezuela, who's aiming down the ground while you are sitting comfortably at your couch in London, UK. Yeah, technically the barrel of that gun points directly towards you, but that exclamation is missing some key parts, isn't it?

Yeah. I'm genuinely surprised that they don't seem to be up to their old tricks. They used to be so involved in places like South America or Middle East.

Has me worried what they're up to instead, you see.

What the fuck is CIA doing, isn't it their job to help people in such situations?
