There probably are many advanced civilizations. And the chances of them even being in our galaxy are probably close to zero.

Would love to see your probability equation... based on an estimated number of planets and the timelines of their origin. (second generation stars/planets - formed from a supernova)

Have you actually done that?(really)

I don’t know why it wold be close to zero. Earth has had numerous very close misses of large asteroids and we never detected it or saw it coming until it passed earth. Considering the galaxy is over 100,000 light years in diameter, I don’t know how we could detect life say, 88,000 light years away, on the other side of the galaxy.

I would think that if life was able to spring up anywhere (other than Earth) then it would be virtually everywhere. On Earth, life can be found in every extreme climate/environment this planet has to offer. Wouldn't it follow the same concept everywhere else?
