You’re stretching it way too far. Most adults don’t have all those, let alone “reasonably intelligent” children. There were child geniuses before, too.
To be fair, there's an awful lot a not particularly intelligent high school child is taught about biology that Aristotle, who clearly was a genius, didn't when trying to synthesize the existing knowledge of everyone he met and come up with new ideas from his own observations.
It's unlikely Aristotle made the mistake of thinking that because other people generally weren't writing this stuff down that meant the world was an uncomplicated place
