 Maybe something happened in the past and people connected things ? and They kept telling others about it?

don't know

I guess from ancient time when people believed in gods (like God of sun and atc.)

Maybe some as a joke that became real, maybe some were intentional to "prove" something they "want" to believe

I don't know exactly but I guess it comes from generations.

I don't have any idea :(

Where do you think superstitions come from?
