If the universe is infinitely old, how did Today ever get here?

How can time measure infinity?

That's a question the advocates of an eternal and infinitely old universe have to answer. An infinitely old universe doesn't make logical sense to me, as I have indicated here from the first post. What makes sense to me is a universe finite in age.

You are using "infinite" is way I am not. A finite universe is not infinite. The universe always existing is not a time sense--it does not exist IN time.

That is a question that sounds like a conundrum but is it really? If it is infinite then being present on ANY given day is equally "likely" or "unlikely".

Today is just as likely to be a time you exist in as Day 1.

The paradox is the claim that there was an infinite amount of time before today - there's no logical or meaningful reason I can think of to believe we had to go through an infinite amount of days/seconds/time units before we could arrive at today. That is both illogical and irrational.

There is no meaningful distinction between saying time did not exist before the Big Bang versus saying that time and space originated at the Big Bang. Either way you are pointing to a temporal origination.

No. You are saying the big bang occurred in time.

There is no such thing as an "infinite amount of time."

That's not what the scientists who advocate an eternal universe are saying:

Universe May Have Had No Beginning
If a new theory turns out to be true, the universe may not have started with a bang.
In the new formulation, the universe was never a singularity, or an infinitely small and infinitely dense point of matter. In fact, the universe may have no beginning at all.
"Our theory suggests that the age of the universe could be infinite," said study co-author Saurya Das, a theoretical physicist at the University of Lethbridge in Alberta, Canada.

You keep using phrase, "in time." The universe exists. Time is a function of existence

The scientists who advocate this theory say the age of the universe could be infinite. The word "age" is a temporal agent, indicating the passage of time.

If you're saying there was no space and no time before the Big Bang, you're literally talking about 'nothingness', and that's not the universe. It's not meaningful to try to compare nothingness to the universe.

So if time and space didn't exist until some finite period in the past, such as the Big Bang, then the universe cannot be infinitely old.

Reaching back prior to the Big Bang and trying to add a timeless and spaceless pure 'nothingness' to the history of the universe is a religious concept, straight out of Genesis.

What is special about today?

I don't ask that to be problematic but rather to point up the concept that if the universe is infinite in time then any point along that time line is as likely as any other.

Which means today is possibly the ONLY day that does exist.

And I haven't even taken an edible today!

Genesis has no such passage or description.

A universe has no day or night, Gunky.

Okay. If the Theory of the Big Bang makes more sense to you, what triggered the Big Bang? How can that trigger exist outside of the universe so created?
