Oh no not another free will thread.

[Edwardo Piet]

Time can't be eternal without start, has been proven on many philosophical levels

We disagree there. To say that there was a time before time began doesn't make sense, because the whole concept of "before" Is temporal.

There was no time before time, obviously. What would it mean for time itself to begin if there were no beginnings before time existed?

If the future has not already been created, in what sense does it exist?  I think you're trying to have your cake and eat it, too.

In the sense that it will come, unless time ceases.

Right. The future will come, it will exist, but it doesn't exist yet. That's presentism and that's what I subscribe to.
