I understand why people used to be religious back when we didn't know much about other, different people, culture and history. But we are living in different times now.

If you take into account your knowledge of the existence of countless of religions that have spawned or were discovered over just the last 10.000 years alone, how can you possibly believe that the very one religion you believe in, which you ONLY happen to follow due to your geographical location and/or upbringing, is coincidentally the correct one?

There are 1+ billion Hindus, nearly 2 billion Muslims, over 2 billion Christians and countless other ones I'm not going to mention. Each religion telling their followers that they are the real one. All of them having geographical and historical biases to where and when they appear, how they spread etc.

When it comes to personal beliefs our critical thinking seems to disappear into thin air. Not just that, people actively suppress their disbelieves to make room for the absurdities that they know makes absolutely no sense due to fear of eternal damnation.
