Hey guys, what are your thoughts on the existence of extraterrestrial life and the potential involvement of governments in concealing or studying such entities.

Hey, I don't know if we even have to argue, your math checks out. But, is 425 years really insurmountable? The first Earth-like planets could be billions of years older than ours. IIRC Fermi himself estimated 3 million to settle the whole galaxy.

The next galaxy is the Andromeda galaxy. It is 2.5 million light years away. There could be life over there right now, but we wouldn’t know, until about 2.5 million years from now.

Let's go by light cones and local interval (clock time in one's own reference frame), if we are going to argue. This shit can get so confusing if we try to define "now", especially if a relativistically fast ship comes up.
