God is one, but people argue about their own perception.
What god is the one? There are like 4k+ gods... I don't know of which one do you speak of.
Wrong. There is only one God. There are many descriptions of God. There are many idols. There are many people who suggest there are many gods. But there is only one God.

How one God could do for different people? And how do you know what your religion is correct? For me this is further proof that there is no God. All religious dogma invented by people and they have no scientific justification.
