(25,862 posts)Although our galaxy seems to have been formed pretty early on, but none of the very first stars formed are still around.
I don't know where you find the 400-500 billion star estimate for this galaxy, since the consensus number seems to be 300 billion.
And yeah, we haven't much of a clue just how long it might take for intelligent life to evolve in any particular place.
Your question of his accepting the Big Bang Theory is rather patronizing, to say the least. In fact, we often have conversations about the conditions of the Universe in the microseconds after the Big Bang. We talk about stuff like that all the time.
Dark matter is the best explanation for a lot about the Universe, so yeah, it's a well accepted construct. As for the speed of light being the ultimate speed, well so far nothing going faster has been reliably found. And yes, I do understand that scientific knowledge changes all the time, so maybe that will turn out to be a guideline, not an inviolable speed limit.
But there's far less evidence for god-like intelligent creatures out there than there is for dark matter, so I'm going to wait for more indications before I'm willing to even hypothesize them.
