Let's confirm that we are referring to the same thing. I see 'endless time' meaning that time had no beginning, stretching into an eternal past. Are you saying that such a quantity of seconds therein is an approximation for a large number?

My concept of eternity is as I stated above. Not merely a large number of seconds.

If space is finite, then the number of objects cannot be infinite. On the other hand, if space is infinite then there is no limit to the number of particles that may occupy it. I don't know if you can have an infinite amount of time, but it seems to be a reasonable concept.
