Human beings do not create God,it’s the other way around,God created human beings .
We humans in our effort to explain God and his world ,and his thoughts create this theories we call religions, and then we establish that they are the absolute truth.
If you take a look at the oldest religions like catholic or Jewish they have changed trough out the years , in other words as the leaders of the religion change so does the religion ,proving that the religion comes from them in their efforts to explain God.
That doesn't mean that they are completely wrong , it just means that they do not have the complete truth ,only a partial truth .I don’t think we will ever have the complete truth. The main characteristic that anybody has to have to get to a more complete truth is honesty. Being honest and not being afraid to find the truth is the only way to find the truth.
Most people that already belong to a religion are afraid to disagree with the religion members or leaders because they might be singled out as unbelievers , they will be judged and will be found to be guilty.
