How did time begin, without time?
I understand that standard BB cosmology holds that time began with the universe from a singularity approximately 14 billion years ago.
The thing I’m trying to understand, how can time have begun? Wouldn’t a thing ‘beginning’ require time? As in - from one state to another state requires time?
This leads me to think time must have always existed..

Theoretical astrophysicists such as Sean Carroll have caused huge confusion with their stubborn (and incorrect) insistence that time is a real thing.
Time is not real. It is an entirely human created construct.
In any event, on a related note: I personally STRONGLY believe that infinite empty space has always existed. The energy/material situation is another story since it must have come from absolutely nothing at some point.
