New in Manicheism

I’m feeling a bit stressed, but what I’d like to talk about is what I should do as a young person who’s interested in your religion and thinking about conversion. But before that, I’d like to ask you a few questions.

First, are you monotheists or polytheists? Because from what I’ve read (which might not be accurate), Manichaeism was sometimes described as a kind of henotheistic system. So I’d like to ask you about that, and also, if you believe in gods, how do you view other deities, like the Roman, Celtic, Egyptian, or Mesopotamian ones?

I’d also like to ask about what I’ve read regarding Manichaeism dividing people into the Elect and the Hearers, how does that work exactly?

Thanks a lot for answering my questions.
