As everyone knows, Idiot America is infested with god-soaked idiots.

Why do billions of people think a god is real even though this the 21st century?

This was the best answer:

Humans are social creatures. We feel better when we are part of a group with a common goal. Religion evolved because we started asking questions about natural phenomenon such as rain, thunder and the sun. We invented God(s) to stand in for these things because we didn't know any better. Now that we have science, God belief is obsolete.

Plus the average IQ is 85 and 95% of people have an IQ of below 120 which is "average". In other words, people are stupid. Especially in the United States.
