I hate relativism but like...:
*points at mercury*
*points at vitriol*
*points at sacred warding*
*points at aqueduct system*
*points at iron*
*points at hospitals*
*points at random other innovations*
"Modern Science" developed as a result of archives, microscopes, and philosophy. We have 2/3.
Even then, after we had microscopes et. al, we still made up hocus pocus to explain what the dinosaurs were(, still refused consider that physics might apply to living things, still refused to consider that maybe we shouldn't spray pesticides literally everywhere) until people were like "what if things change bro??" Literally all they need is to realize that evolution is a thing, that their bones aren't the same animal, etc.
They have the bones, they have dogs that are different from each other, it's not the biggest leap.
People work w/ what they have.
