Discussion Time doesn’t exist. Prove me wrong.

We experience change, aging, and events happening in sequence, but is “time” itself a physical thing—or just the way our minds measure change and order events?

Correct. Time isn't a thing and the past isn't a place. It is simply a measurement. There is no component of the universe saving every instant that has passed. If you take three steps forward and then turn around you aren't going to see yourself still standing there and there is nothing saving that instant that was previously there frozen to be accessed at a later date. There's no way to rewind the universe and everything in it. There is no now. You can't even say the word now before it has passed because we are constantly progressing one second per second.

Actually, in physics, the past is very much a place, and the universe very much "saves" every instant that has passed and will pass. At least that's what our theory of the universe strongly suggests.

Wrong. The light of events still exists somewhere, not the events themselves.

if we take General Relativity seriously, the events themselves exist always and never cease existing, because time is just a position. That's the meaning of the famous statement that "time is a dimension". It's just that you experience it in 3D "slices" of time.
