I'm not sure what you mean by there having to be an infinite number of *more* events before any particular moment of time. Where is the 'more'?
So, what we do *NOT* have is a situation
start----infinite time----now.
Instead, we have the situation for any point in the past,
infinite time----point in the past---finite time---now.
Bold mine.
I think what Steve means is, if we have time moving in a forward direction, how do we get to that one point in time from an infinite past? How do you get to that single event in time without beginning somewhere? If events are happening in succession, and time is infinite into the past, how would we ever arrive at a singular point in time? Wouldn’t you have to start somewhere to get there? I’m confused! Lol
You correctly understand my point. Polymath does not because he is so sure that there is not problem with an infinite chain of evens that he doesn't even see the metaphysical impossibility of his statements. He just states them over and over because his math background says you can do math with potentially infinite sets so an actual infinite must exist. If it wasn't so frustrating, it would be a fascinating example on why Philosophy of Science should be the first course math and physics majors should take.

LOL. Sure there are. BTW, you are failing to prove that actual infinities exist. You bring up some potential infinities candidates or that potential infinities are used in some equations--but that is not the same, is it.
