The Aliens evolution problem.
- If aliens reached spaceships, then they evolve - they have a progress-oriented culture.
- At this advanced evolution stage (spaceships), evolution should be very accelerated (AI, computer to brain, gene manipulation…).This means that any aliens with spaceships will evolve towards being undetectable (by us) - very fast.
I don’t think any advanced civilization can spend more than 200 years from having spaceships to being undetectable by us.
Assuming we are visited by aliens since 200 000 years ago (or more?) and considering aliens will evolve very fast to being undetectable, how come we still see them?
Theoretically, we should perceive our (possible) contact with aliens as multiple interactions with different alien species, where each detectable contact cannot span more than 200 years (or so).
(with a discussion on the slow evolution theory)
