Even if time itself has been for ever, there are no inifinite timespans.
In other words: any timepoint is a finite distance frim any other timepoint.
Thus there are no inifinite timspans to ”traverse”.
Thanks for articulating this particular idea. It shows even UM's buncombe has its usefulness, you see.
Still, me, I would disagree with it. I can't find any good reason that an infinity of time in the past couldn't have come with something existing at every one moment along that time span.
Unfortunately, I also can't see anything practical that we could do with this piece of metaphysical wisdom. We already struggle to get past the Big Bang, so infinity is way beyond our reach.
Obviously, it remains true that the time span between any two points in time is finite.

I guess the inherent limitation with our mathematical concept of infinity is that it is broadly speaking algorithmic in nature. Infinity is conceived by mathematicians as the purely notional limit of an unbounded series of terms. In this sense, infinity is not thought of, conceived, as anything like an ontological reality.
The idea of an infinite future doesn't require any new notion of the infinite because we think of the future as something happening one step at a time, much like we can only think of an unbounded series of terms one step at a time, one term coming after another. And we get away with it by imagining that we could continue considering the following terms of the series, one after the other, one at a time, ad infinitum, without ever getting to infinity itself.
Now, the idea of an infinite past seems something different altogether in this respect. The concept of the past as something already done with, seems to require that in the case of an infinite past, infinity has already happened, and therefore that infinity is a full-blown ontological reality, not just a pure abstraction. At any moment in time, including now, there's been an infinity of seconds, and an infinity of millennia, that have already gone by.
This may be something of a problem to get our heads around it. Think of a simple clock. If we try to assume that such a simple clock had always existed, what time would this clock display right now? I'm sure we're all going to be stuck here, like, forever.
Still, I trust this forum packs more brain power within fewer skulls than the current U.S. administration, so despite my own personal limitations in not seeing any way out of this conundrum, I will wait to see if someone else here can come up with an imaginative solution, hopefully one not involving the impossibility of having a clock at every moment in the past.
I'll be waiting for your answers. The clock is already ticking. Don't make me wait till the end of time.
