Occam's razor

Peace and blessings,
 
After a certain person accepted, for example, the physico-theological argument, then he understood that there is a creator(s) for the world.
This is what the argument is about, and it is certainly a strong argument in my opinion after reading it and the appeals to it.
 
Regarding Ockham's razor, I encountered an argument with someone on the following sentence:Let's assume at least two primary beings: God and Satan. You see duality everywhere, you see that nature is governed by a struggle between forces, you see that it is opposition that drives the world forward. Assuming two primary beings explains so much that to claim that you can shave with Occam is ridiculous.
 
What do you think about that? I would be happy to answer.
