That's not actually true. There are archeological records and logical implications based on proveable science that leads to the inescapable conclusion that humans were not "just like this" since the dawn of the Earth.

Okay, so by definition, a theory is a description generalization. It isn't an unproven fact. The term you're confusing for "theory" is "hypothesis". A lot of people make that error.Scientific American said:According to the National Academy of Sciences (NAS), a scientific theory is "a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses." No amount of validation changes a theory into a law, which is a descriptive generalization about nature. So when scientists talk about the theory of evolution--or the atomic theory or the theory of relativity, for that matter--they are not expressing reservations about its truth.

So basically, we have unequivocal, logical proof showing evolution occurs.Scientific American said:In addition to the theory of evolution, meaning the idea of descent with modification, one may also speak of the fact of evolution. The NAS defines a fact as "an observation that has been repeatedly confirmed and for all practical purposes is accepted as 'true.'" The fossil record and abundant other evidence testify that organisms have evolved through time. Although no one observed those transformations, the indirect evidence is clear, unambiguous and compelling.
