Yeah, that's spontaneous generation, a popular theory from Medieval Times. >____<He confused it obviously with another theory but I have no idea what the names of those things are and I don't really care, it produced a funny video though.
As for the reason he thought it proved it wrong was:
according to the theory, life came to be because of energy (and some other things he'd mentioned that I forgot it was ages ago since I saw it).
All these things are present in a pot of peanut butter therefore new life should be able to form inside this pot, then why is it that I never saw a new life form inside a pot of peanut butter.
(and he rambles further and further and further).
Well, he was probably mixing that up with the 'primordial soup' theory/abiogenesis. But none of that has to do with evolution anyway because the Theory of Evolution is about how already existing life changes over time, it doesn't care how the life got there.
