Answer 2

I doubt that theory!
The only way it could ever have existed is if the world was destroyed and all evidence, so it truly was "non esistent"
Conditional probability > Bayes's theorem






Consider now the defining relation for the conditional probability P(An|B), where the Ai are mutually exclusive and their union is the entire sample space. Substitution of P(An)P(B|An) in the numerator of equation (4) and substitution of the right-hand side of the law of total probability in the denominator yields a result known as Bayes's theorem (after the 18th-century English clergyman

Answer 3

yes. all that prehuman knuckle-dragging is a bunch of non sense , man has always been a maximally intelligent being from moment one. and if the Earth is as old as some say then its highly probable that a fully sentient being inhabited this earth prior to modern man.
