The short answer is that gods were originally created (I'm obviously referring to polytheistic religion here) to explain things that mankind had no understanding of. Very simple things. Rain, snow, natural disasters, disease, famine, victories (or losses) in battle, plant growth, et cetera. Yahweh emerged in Jewish tradition as the one true God (or at least, the only God that may be recognized). "Allah" is not a new god because Islam is a monotheistic faith; "Allah" is the Arabic word for "God." By definition, monotheistic faiths cannot invent new gods, only deliver new revelations or prophets.
I agree.
A new prophet, since a person, would just be inventing a new God. That is what Mohammad did.
No, he didn't "invent" a new god. Perhaps consider doing some basic research before you comment on a religion.
A great argument against what I put. That really corrects. Not.
Name another god that gifts it's male adherents with 72 virgins after death if Allah is not a new god.

Nobody even remotely serious about studying comparative religions would claim that
this was enough to make a figure 'a new god', and there are a
lot of ridiculous serious claims floating around in comparative religions.
