Your premise, that there is no god, fails to explain why there are believers in this world.
My premise, like yours, is only there to explain your belief, that of others.
Wrong. There are many natural ways for people to come to the conclusion that there are gods, like how people thought the earth was flat or the earth was the middle of the universe. When people are faced with things they can't explain, it doesn't take much to come up with stories (certainly not if you have time

). People love stories, and people started thinking they were real and did all sorts of strange things with it (even sacrifices).
No god is the most sensible explanation and doesn't contradict anything and there's no evidence against it.
Nope, all I have to do is show why "my" God is the true God. By default, you'd show all others to be wrong since there can only be one Almighty God anyway.
Exactly, but despite the fact that there are billions of people who believe or have believed in one or more gods, there is not a single piece of evidence. Therefor, there's no reason why the most sensible explanation (no supernatural etc.) and also the explanation with the most evidence, isn't correct.
Like you said earlier, wrong premises lead to wrong conclusions. The best way to gain knowledge is not to use any premises at all. Science starts with no knowledge at all, and if you think you have, you'll have to prove it. That's sort of Occam's Razor.
So show me why your god is the true god...
Simply saying "your god is made up" doesn't mean anything. Really, that's the only answer atheists offer.
I'm not saying that that is the answer. But that is the conclusion that you make for all other gods. From the famous quote: I contend that we are both atheists. I just believe in one fewer god than you do. When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours.
See, this is predicated on the opinion that my answer would be "because your god is made up".
That's not an opinion, but a logical conclusion when you say that there's only 1 god.
Additionally, this is where logic and reality clash. You can apply whatever you want to "my" religion, doesn't prove anything as regards the existence/non-existence of God. I can do the same, won't change anything.
Yes, it does. If your religion/god can't explain why other gods -- like gods/religions that were invented before your religion/god came into existence -- exists, that means it can't explain reality and is fundamentally failed, in fact disproved. Unless you do prove that your god exists, but since that hasn't ever happened, it logically follows that god doesn't exist.
