This is an insult in case you do not understand that.
Nope, it's just a statement of things you have already done. Fancy denying that?
For something to be real it has to be able to exist.
You are
so going to hate the Banach Tarski paradox...

I'm afraid there is more than one way of being real.
You cannot write out all the fractions between zero and one.
Sure and yet Cantor's diagonalisation proof:
https://en.wikipedia.org/wiki/Cantor's_diagonal_argument
But you can say they are logically all there. You can imagine they exist.
No, I think you can formally prove that they all exist within a mathematical ontology. You really do need to be careful with your use of langauge.
No infinity could have real existence. It is not a concept that could be real in any way.
I think at this point I really need to see your definition of
real I suspect that it's the problem here.
If you imagine any item that takes up space and claim you have an infinite amount of them they would completely fill this universe and infinite other universes. Nothing could contain them.
Sure, and your point is?
Time is something that "passes". We measure it with clocks. So it is something that can be measured.
No, we don't measure time with clocks. That's a common misunderstanding. Like language, we have a common agreement as to what time and indeed the time is. Any watch or clock is merely tuned to run at the same rate as all the other clocks, currently based on signals sent from atomic clocks from Colorado, Rugby and so on. Their authority is entirely conventional and doesn't even agree with the time derived from the movement of the solar system - there's an equation for converting them, the Equation of Time.
At this point I have a diagnostic question: does the statement: 'the universe stopped for ten seconds' make sense. If you think it does, you think time is independent of the universe and are a time dualist. If you don't then you are a time monist.
But there cannot have been infinite time in the past.
Well that's the key move. Why not? You havben't made any argument for this central claim.
That is an amount of time that cannot be measured. It cannot have 'passed'.
Why not. Even with no one to measure it, the universe would have happily carried on and that carrying on is to me (a time monist) is time passing.
If you say "infinite time occurred before yesterday" you are saying a measurement of time that cannot ever be made occurred before yesterday.
If you are saying that humans measuring it is the basis of time passing then you are really going to struggle to explain any change before we existed. Time is change, that's it.
If a measurement of time that cannot ever be made must occur before yesterday could occur then yesterday can never occur.
Looks to me like the universe was measuring it for us by carrying on as it did, following the laws we are now coming to understand. If a fully wound pocket watch had sprung into existence seven billion years ago, due to some very unlikely quantum event, what would you call it's hands going around.
Now, as we are talking about time, have a nice picture of one of the world's first quartz watches, from 1971:
