Ok, that's a lot to respond to. First, minor thing, "evidence" is an uncountable noun. There is no plural. You might have "pieces of evidence", but not "evidences". Doesn't effect anything, that's just a common mistake.
To the point, I'm not saying that knowledge causes anything. I never did. What knowledge does is prevent other possibilities. If you know that the sun will rise tomorrow with absolute certainty, that won't directly cause the sun to rise, but it means that any situation that would cause the sun to not rise is impossible.
Similarly, knowing that you will choose chocolate ice cream doesn't make you choose it, but it makes it impossible for you to choose anything else. By having knowledge of all future events, the number of possible outcomes for any choice is reduced to one, the one that god knows will be taken.
If every choice has only one possible outcome, then there is no choice. No other option could possibly be taken. If you can't make any choice, you don't have free will.
