This question already has an answer here:
Is there a general consensus about whether the universe is deterministic? Is it still up in the air?
I have attempted to read other physics.stackexchange answers and do some independent research, but I'm not a physicist and most literature is beyond my comprehension. If you answer this question, I would most appreciate it if you could attempt to explain it as simply as possible. As soon as I have to start to look up theories or definitions that are used, the web pages that explain it generally go over my head.
The easiest way to phrase my question that I can think of:
Assume there is a being existing prior to the big bang, with infinite intelligence, physics knowledge, memory, and time. The only limitation is this being can not time travel to observe the future universe. However, this being knows everything about everything as it currently stands. Once the big bang happens, could this being map out every interaction in our universe throughout all time?
