so they’re going with Aliens created life on Earth
...
But how did the aliens get here? I’d prefer one of the anthropomorphic (I don’t know if that’s the right word.) theories before aliens. I also like Asimov’s idea he used for the Last Question.
They snuck over the event horizon.
Panspermia theory just creates more questions because there is now the question of how those aliens came around, and more.
It’s aliens; all the way down.
