Is There No Such Thing as Zeus?

How does religion incorporate the concept of myth? So, for example, there are several religions which will say that dinosaurs are a myth. They're like, they are a test from God, because it doesn't fit in to their teachings. The idea that actually Zeus just never existed at all comes much later in Christianity and Islam. But then, once you get to the early 20th century, anyway, the idea that somehow myths of this sort of key to understanding some universal features of human culture is really popular. And I think probably the most influential elements of that idea still survive other psychological theories.
