Also, if time does exist, doesn’t there have to be a definable beginning or end? Otherwise it’s just infinity which to me suggests the absense of time.
I partially read “The Discoverers” by Daniel Boorstin several years ago and he discussed how different societies conceptualized of time and how they kept time. And it has had me wondering ever since. Then I started exploring Zen Buddhism which emphasizes the present moment as the only tangible reality, along with the illusion of the ego, which only furthered my questioning.
EDIT – I am aware that the concept of time is based on the revolution of the Earth and it’s moon. However, that is just how humans conceive of time. That’s not proof of time itself.
EDIT 2 – The explanation of timespace and relativity is the best from an objective point of view. No matter how much I read or watch, it was always a bit hard to grasp but it makes sense in terms of change or entropy. The reality of time being flexible vs the human perception of time being linear and unchangeable gets closer to what I am asking.
EDIT 3 – “Exist” is a tricky word.

Time is an essential part of 4 dimensional existence according to einstein, you can have a 3 dimensional universe where everything is reacting the same as ours but without time those reactions and subsequent movements don’t take place. Therefore in 4 dimensions, time is space and space is time, they are inseparable ideas. Without time there is no space because the universe simply never exists. Without the universe there is no time because there is no passage of space for it to measure. Not sure that explains it all that well but I tried to get it to eli5 level. But basically, yes, time is real.
