Cosmological Struggle: Bible Is Just Propaganda Against Satan

What if Satan and Yahweh are not who they seem? What if Satan was not a fallen angel, but, like Yahweh, a creator of sorts? It seems in lot of the dead religions, good versus evil had equal forces, thus both could exist separately. That is not the case with Christianity, Yahweh allows Satan to exist and be evil.... for whatever purpose, but that's not the point of this. What if they are just two sides of the same coin?
Here's my idea:

Now, firstly, I don't know how they came about, but I'll assume there was a whole race of people like Yahweh and Satan, who for the purposes of this story has the exact same powers as Yahweh, and that they either died out or are given divisions above "garden" or life sustaining planets of inferior and primitive species. Satan and Yahweh were given Earth to have domain over. Now, with this theory I can't explain much..... but I'll just do the Christian thing and say that my finite, limited, mortal brain can't even possibly conceive of the glory of Yahweh and Satan. What I want to focus on here is the book and how it intentionally treats Satan as an inferior creature, even though he has the opposite "job" of God and that's maintaining Hell (personally, I think that, in the context of the accepted idea of God, he just couldn't be bothered with the upkeep in Hell, especially since he's used to dealing with the very exclusive ELITIST club of Heaven). It's just propaganda.

See, they say Hell is an evil place where you will burn for eternity and is hot and basically appeals to the fears and emotions of the weak-minded. Fire, which was still a remarkable discovery in those days, is magical and symbolizes burning and the pain that goes along with it. Also of the most excruciating pain you've ever felt..... without saying how or why. Yet it's infinite, we cannot die, but pain is basically "killing" the body, so this doesn't make sense. But I digress. What if it's just Yahweh writing propaganda against his competitor? You see this between the same businesses in a particular region. Attack ads and such. The duties of Satan, maybe they don't allow for him to speak to people or interact, thus Yahweh can make him seem as he pleases.

Also, look at what God has you do to get into Heaven. I bet 95% percent of Christians won't get in, at least 30% on ONE mistake, alone. All that praying and praising and preaching..... to an egotistical maniac. And when you get there, you're the only person you know there! Yet what are the qualifications for going to Hell? Doing stuff, taking risks, making advancements, fuck, even enjoying life will get you there. What if Hell merely symbolizes reality as we know it? What if Hell is just another "club" like Heaven? Ha, even on the occupants alone, I'd rather be in Hell than Heaven. But notice how first, Hell is not descript, just described as an appeal to emotion, also the huuuuuge list of things NOT to do to get into Heaven, and also how many of your friends and family most likely, won't make it to the Yahweh's jerkfest in the clouds.

Bonus note: What if Satan corrupted the message of Heaven? I mean, the qualifications are impossible to be held, by a mortal, normal being but he couldn't just say Hell is cool, maybe that would be breaking some cosmological pact that the deities made. Instead he has to vaguely say how bad Hell is to sort of equal it out.

Hmmm, something to think about.
