Just going by pure math conjecture it's unlikely there is intelligent life remotely similar to us in our galaxy. Supposing it takes ten thousand years for a technological civilization to double the number of planets it occupies. In that case it will fill the galaxy in less than a million years, so for two species to meet before one dies out or prevents the other from evolving they have to arise within the same million year period. In a galaxy over thirteen billion years old that's quite unlikely.
- TheOtherHobbes 7y agoThere is no pure math in this space - just hand-waving and conjecture. We have exactly no information about xeno-evolution. It's not even a given that aliens would be motivated to colonise the galaxy, or that they'd do it in a way that would be recognisable to us. It's hard enough to predict where human civilisation is going to be fifty years from now. The idea that we have any clue what an alien civilisation will do over millions of years is... unconvincing.
