No science is based on explanations that are hard to vary (i.e. explain what they purport to without any competing explanations).

We use scientific experimentations not to prove but to rule out alternative theories.

I can explain why a given thing will act a certain way. I don't need probabilities for that.

If I need probability it's because I am just guessing and nothing else.

If I need them I am just dressing up guessing in fancy words. But I am just that.
