OH, you want to play the NUMBERS game?
There are an estimated 9500 variant species of dung beetle in the world, making them a quite populous species. The population of dung beetles world-wide is probably in the billions. So... let's play a numbers game. 50 billion dung beetles are going to eat

tonight. Will you join them?
The problem with numbers is not that some number of people believe. Remember how militant some of those groups are when you are shown to be a non-believer. Remember that children are taught during a time when their beliefs are malleable. It is not accidental that Jesus said, "Suffer the little children to come to me." And suffer they did. Some of them - me included - suffered cognitive dissonance when we got old enough to think like adults and suddenly question some of the things we had been taught. The dissonance comes about when you realize that your parents LIED to you about God's existence. (You learn to forgive them when you realize that your grandparents lied to your parents...) Think about religion throughout history and its - shall we say INTENSE - attitude towards those resistant to following the party line on beliefs.
Let's not even begin to think about the Islamic world where in many nations TODAY, apostasy is a capital crime. Can you count those people as true believers or subjugated slaves of religion? Think back further in time to consider the Inquisitions? Or consider those days in other nations where their emperor was considered to be a walking god on Earth.
Religion makes a point about "free will" - but a lot of the time your ability to exercise free will in believing or NOT believing was simply not your choice. You had the "free will" to believe as the power hierarchy wanted you to believe. But again, can you count those people as believers or as frightened people afraid to be non-conformant?
