To us humans, of course it does. It’s bleeding obvious. And not only do we age in time, but so do physical objects. So there, it’s proven, time does exist.
However, I can’t stop thinking, that at the sub-atomic level, particles exist, and continue to exist, irrespective of time, and therefore have no concept of aging, in fact their existence may create time, or does time create their existence!!
Mind you, if a black hole comes sweeping past these sub-atomic particles, they’ll soon learn what time is! Or maybe not. What happens to particles inside a black hole? Does time exist inside a black hole?
