We used to worship the sun in Europe too. But Christians decided they wanted to test that resolve, when they were helping pagans simulate the conditions of the sun by setting them on fire.
Technically you still do, Jesus basically just consumed Sol Invictus and his cult practices to be palatable to the Roman public.
Same Birthday, same halo iconography, same vision to Constantine at the Milvian Bridge. No seriously, that was originally Sol Invictus before Constantine fully embraced Christianity. The Chai Rho was a symbol of the general concept of righteousness at the time and was used by Constantine because it was a symbol all his multi-faith forces could accept as being a divine message without rubbing them the wrong way for being too partial to one religion or the other.
paganism works well with monotheism if you imagine that all could be a potential avatar of or personification of an overarching identity or deity which has multiple sub personalities due to omnipresence across multiple universes or timelines
This is the answer to the question I was always wondering about: "It's obvious to me that Catholicism is a corruption of Christianity due to mixing with Roman religion; but what are the exact details, and how did that even come to be?"
