The Direction of Time
I think time itself has a direction. It would be even harder to deny the existence of time altogether. Simply saying time has a direction would not explain all by itself any of those observable temporal asymmetries are what people sometimes call arrows of time. So I think all of that is a perfectly good object of study, even if you believe as I do, that one of the things you can invoke is that time is itself directed. That doesn't give me these observable asymmetries like that, but it might be part of the explanation. How does it help?
