This is a bit of a semantic game, but you need to differentiate between causality in the universe and uncertainty.

I agree, the universal is causal in nature, based on a set of reactions that abide by the physical laws that founded it. There's still uncertainty for every observer in the universe, though, as this uncertainty is built right into those very laws that link the universe causally (See quantum mechanics, e.g. heisenberg uncertainty).

This can be hard to understand, but in a nutshell the causally linked rules of the universe that ultimately always determine what happens next can never be fully known. There is always uncertain information that is changed and influenced by any and all attempts to know this information. As such, it's a bit like the universe can't really make up it's mind.


Anyway, this has very little to do with the OPs original argument.
