Why I Can’t

If God left everything to run on its own, and gave people the ability to choose what was not necessitated to take place, then God didn’t know a certain future. However, if He knew a certain future, then it must happen that way, and people are not free to choose differently. But if people could choose differently, then it wasn’t foreknown to be, and God isn’t all-knowing. Why take a view that degrades God and elevates man?
