I have a way to explain the happen statement.

I think the word "eventually" is helpful. For example...

Even though we can't see which path the universe will follow (and therefore we have a number of possible outcomes), eventually time will progress to completion, and then everything will eventually have followed a particular path. Consequently, there will eventually be a particular array of decisions made that can't be unmade since they will eventually be in the past.

Even considering time travel. Whatever you changed in the past will become the new past, and eventually time will run out for such a civilization and they will then be unable to change anything anymore. Hence a particular path will have been followed, even though we can't tell what it is yet.

In a logic syllogism you can phrase it this way: If the past cannot be changed, and time will eventually end, then our decisions will eventually be unchangeable, therefore we will make a specific array of decisions.

You might say, yes "eventually," but that has no bearing on the present, where we make decisions. That's like saying that just because something hasn't happend yet, it isn't true. For example, the statement "the sun might not rise tomorrow" is true because we don't know for sure that the sun will rise tomorrow, we just have lots of evidence for it. It's the difference between inductive and deductive logic.

Conclusion, fate exists in a passive way that does not affect our control over our lives. It simply occurs using the definitions of words we have in conjuction with logic.

Please challenge me. I apologize if I sound pretensious.
