Most people do believe in some sort of god concept, true. But that itself is not proof to prove god. It's also true that most people who believe in some sort of god hold that most other people who believe in god are wrong. Even within Christianity, this puts you in a very slim portion of those who agree with you while the overwhelming majority of other Christians say you are wrong.
So have two statements:
Most people believe in god - true
Most people who believe in god think their belief is the only correct view - true
These two statements are both true. But most people believing in god cannot alone make god true because it is also true that most people will reject the religion of any one random individual from this group as true. Thus, it would follow that if commonality of a belief makes the belief true, we are left with a logical shortcoming as most people will say the religion of any one random person is wrong, something that should say god is not real as that is what most people believe (because ultimately no ones god would stand undismissed), but, yet, somehow because people do believe in some sort of god, so what are we left with?
The very fact most people do not agree as to what a god or afterlife is, their nature, and existence (or, morality, as I believe we were discussing), or the fact that god must be real because most people believe in a god? They obviously both cannot be true, but yet both have accuracy their
We would need to talk about "weak correlation" and "strong correlation". For example, there is an immensely strong correlation between being a person and believing in a living God or gods.
statements that make appeals to popularity. That is why any argument based upon how many people follow or like or adhere to something proves absolutely nothing more than the number of people who participate.
And that is before we get to science. Correlation does not mean causation, and correlations do not ever prove anything. Such as, there is a good correlation between having Asperger's (and I've also read autism in general) and not believing in god. This is why wording is very important in science, because your statement would imply those such as myself are not a person because we have a higher correlation in the opposite direction. But our lack of belief (or anyone's) does not make us less of a person. Scientists are another group that has a higher correlation of not being religious/theist, but that does not mean a scientist will be an atheist/agnostic, and indeed there are many religious and spiritual scientists out there. Which also goes back to just because something has a higher correlation or more of widely held/popular belief does not necessarily make the statement true outside of looking at how many people follow/like a certain thing.
