How so? God exists simultaneously at all the moments that exist. Time was created by God, just like the universe was.

Imagine you are writing a book, where you, as the author, are also a character. You can interact with your characters as they do things - but you can also go back and change anything you want, and you can see the ending as well.
(Keep in mind that God always maintains free will - God doesn't force any human to act in any particular way, it's always their own choice.)
