Sure it does!
Aah… now you’re asking a completely different question! You aren’t asking “does the future exist?”, but rather “do we know the content of the future?”…!!!
However, that wasn’t your point: you are attempting to show the former, but are only able to demonstrate the latter. And the problem is that the latter does not imply the former.
However, that does not mean either that this future exists – or that God does not know!
Yes, knowledge of the future is inaccessible to humans. No, this doesn’t imply that the future “only exists in the mind of God.” I’d agree that God possesses knowledge of the future, but not that it does not exist, per se.
Right. In this case, the best that can be asserted is a conditional: “if I choose to board the plane to Chigago, then I will be injured.” However, choosing not to board the plane is not a way to thwart a prediction; rather, it’s merely a way to choose among a variety of options.
