Oh no not another free will thread.

You do get the concept that a choice requires more than one possible outcome though, right? If the only thing that you can possibly do is X... what kind of choice is that?

If a being knows with absolute certainty that you will do X... how could you do Y?

Here's where I think your logic fails.

Being knows I will choose X over Y.
What precisely is preventing me from choosing Y over X?
Anything?
No, nothing.

A being's knowledge is not certainty. It's merely a reflection of what could be.
