Time exists in this physical realm. So I does indeed have a beginning. Though other realms can be timeless - for example where the creator exists which means this being has always....
time is relative in macro-scale which IMO already gets shady; quantum-level physics is cray, but i'm not mistaken time is not even a thing there & in reality, everything is quantum ⏳
I would tend to believe that the only reason time always progresses forward is just because we don't know how to go backwards instead or faster forward.
