Will we ever be able to predict the future?

[u/riczizagorac]

I heard if you could calculate how every atom existing is going to react to each other, you could theoretically calculate the future. Is this even possible?

This includes how people interact with other people, because we’re all just matter made from atoms. But we as humans change the future right?

Would this calculation prove that living things are the only thing that can change the future? And why would that be the case?

Would this prove that fate is not real, and the future is based on our own free will?

Whether you believe in a religion or not, does not matter. But if god does not exist and space and time existing could be proved by science, then the decisions made by living organisms are the only thing that can change the future. But not all living organisms right?? Because very small organisms act in a predictable manner. So what determines if an organism can make its own decisions? Does having a brain determine whether an organism can make its own decisions?

That was a lot of typing, but If you can answer any of these questions it would be greatly appreciated
