Indeed... Very much so. “This would be worrisome from a Great Filter perspective.”

Indeed… Very much so.

If, as you suggest, life on earth originated elsewhere, then that strongly implies that a few 100My is not long enough for it to emerge (else we wouldn't need the panspermia hypothesis).

So what? Isn't it far better for us to invest intellectual energy into making something tangible or useful? The point is that most academic curiosities aren't really useful to society, but merely serve as arbitrary in-group mores. OK, so you manage to pinpoint the exact point for origin of life. So what?

Kauffman. The idea is compatible with the early emergence of life on Earth. So, the idea that early life is necessarily complex is a long way from being established - and so represents correspondingly weak evidence.

We've also performed major geophysical engineering; Mt Rushmore won't last forever, but that'd piddly compared to stripping the planet of resources like fossil fuels that a future prospector would expect to find. So if there was sentient life on the planet prior to humans, they certainly didn't nuke themselves into extinction.

If such claims were verified, they'd be clear proof. Some claim to have found fossils of life on meteors that are older than Earth. If such claims were verified, they’d be clear proof.
