The real question here is what is time. We don’t know. In the way we understand the world, there is a thing we call “causality” and we postulate that the whole universe abides by it. And by this causality we can reason and explain “everything” so far.

This causality thing though needs stuff to be ordered (first A happened, then B followed, then C , …). And now you have time. And since we haven’t seen causality go the other way (broken vase -> vase), we say time doesn’t go the other way either.

And it turns out that time works really well in order to explain things, because since Einstein we’ve added it with space and we got spacetime.
