Ouroboros
Coincidentia oppositorum
Sure.Only if you assume that Gods dont exist and that these claimed events didnt take place.
The alternative is that the first theists got the information and ideas from an actual God(s), in a revelation. And then they wouldn't be implied theists, but quite explicit in their beliefs from get-go.
Now, even so, it is possible that some people, in some regions on our planet didn't have a revelation from God but grew the idea (implicitly) over time before the concepts were formalized.
