If I tell you A happened before B, you can always ask what happened before A.
For example, imagine the sequence of events `A, B, C`. After `C`, imagine that the cycle repeats with the beginning of `A` again, ad infinitum.
Also,i feel there are no satisfactory answers here. See also https://en.m.wikipedia.org/wiki/Unmoved_mover
That concept is easy to say, but very difficult to mentally accept. We’re too accustomed to thinking of time linearly since we’ve never had examples to the contrary.
For starters, linear things can be infinite too (e.g. integers). Being cyclic and being infinite are separate.
Second, I do not know if time is finite or not, but i do know it lasts longer than i do, and anything that does is essentially infinite from my perspective.
Is a time crystal a counter example? Guess its not something we would normally encounter anyways.
Maybe cyclicality or just from nothing are only real answers. Illogical as they may seem, in the end something from absolutely nothing would probably solve the problem.
That it understands any part of it at all is already more than can be expected from mere matter.
And that something does not make sense to the human mind doesn't mean that it can not be.
