>>149458038Personally i think this intro is wrong or has incomplete information, DC has had metahumans in it's history for way longer from Black Adam, Vandal Savage, Ras al ghul, Nabu, every Hawkcarnation and Aurakles. I imagine this is just when the superhuman anthropologists identified the first confirmed superbeings.
If i were to make my own super world with metahuman anthropology or some shit i'd make sure there was a heavily flawed historical era chart, lots of flaws like "being too westernized" and "having a biased view of history" (or categorizing history too much or too broadly). Starting with the age of myth and legends, mythical heroes like Hercules and Gilgamesh and such, then going to like.. an age of "legends" being the late antiquity and late medieval period, an era of "adventurers" being the modern period before, the subsequent pulp and spandex eras takeover in the later 1800s and 21st century.
Figures like King Arthur would be a point of contention because going by superhero logic he was probably real with magic, but it was more nuanced than that, hence a criticism of categorizing metahuman history too much.
