What does it matter? Would you change anything? Could you?
Laplace's Daemon is a conjecture by the great mathematician that there could be a being, or a machine, a mind large enough to comprehend everything in the universe right now, which would then be able to apply the laws of physics and mathematics to determine any situation in the future. Laplace unfortunately didn't know about Quantum Physics which has a principle that effectively means that you can't know both where everything is and where it is going, at the same instant. So the Daemon could never know the starting point that would enable it to conjecture the future.
Even if you knew all the laws of physics, those same laws mean you can't predict the future with any detail because you can only guess the starting point. So, if everything is fated, we can't test that - we'll never know. So fate or free will, we'll never know the outcome, and therefore choose the one you prefer to believe!
I like to think I choose to look both ways before crossing.
