The root cause of everything is the laws of physics and, to the extent it is a separate issue, the initial state of the universe.

Or, from a different epistemological viewpoint, the root cause of everything is God’s will.

Ascribing importance to intermediate causes is highly subjective, even assuming they can be reliably determined.

Only if you think that the laws of physics are deterministic, I guess.
