What I don't see being brought up often.. So, the universe could be infinite right? Or at least many orders of magnitude larger than the "visible universe"?

If that's the case, the occurance rate of life could be very very small, and we are still practically gaurenteed to exist, along with many (infinite) more life.

But it's entirely possible that they are all over a "visible universe"'s distance away. Which with an expanding universe, would mean that we could never meet or even observe them.

In some ways, that's maybe more lonely, or at least sad, than being entirely alone.
