@Justicar It was a part of their tribal identity. All religions are based on stories/myths from other cultures, including Abrahamic religions, they're no different. The story of Jesus is very similar to that of Horus, for instance. Nothing "new" about it.
They weren't "pagan gods", they were Gods, same as any other, same as the Jewish God that Noahide gentile now accept.
They didn't have a name for the religion, because it was theirs.
Until Christianity. Out with the Old and in with the Jew.
