The probability of the accuracy of probability itself? Etc.

[Darwinian]

Yeah that is exactly what I said my friend probability is not 100% accurate it's just an educated guess about what is the most likely answer.It's a high probability that since the sun rises and sets every day for the past 12 billion years it will most likely rise again tommorow.Just educated guesses based on past knowledge and experience depending on what it is you are trying to prove or disprove.

Actually it's 4.5 billion years. Give or take.

Not that I'm be pedantic
