Hi, thanks for your reply...
But what is their proof that these things are actually uncaused, versus the possibility that the mechanism is simply unknown?
There is none, and there can be none...
The null hypothesis states that is it impossible to prove an absence of something, such as cause.
So it's logically impossible for the things you mention to have been proven to be 'uncaused'... You are mistaken.
Causality cannot be 'disproven' by science, because proof requires causality...!!!

You have proven my point that modern science is a religion resting on faith and belief, and it's followers are unfamiliar with logic. Thank you.
