I saw several mentions on SFF that Namor was the first mutant.
Yet, from ComicVine
Led by Azazel, the Neyaphem are a group of mutants with demonic appearances. Existing since biblical times, the Neyaphem believed humans to be inferior and should be used and/or killed.
That definitely makes him not the first (IIRC he ws born in 1920?) by something like a couple of millenia?
How can this be reconciled?
