I understand that most people are afraid to believe that God is real, because the idea of God being in control of our lives is really unnerving. The idea of hell alone is scary enough. For me, the simplest explanation is to use your inner voice or gut instincts. Just because we can't see God, doesn't mean that He does not exist. We can't see the air but it exists. We can't touch the light but it exists. Naming the creator who created the universe as God is acceptable or decent enough. His real name might not be God, but He, as the creator, exists. We are like animals with limited knowledge about the world no matter how far our technologies have advanced. I respect humanitarian religions because they contribute on the balance between good and evil. Without them, this world will be charged with war and chaos. Also, moralism and humanism will be absent or will become invaluable. The world will be an inferno.
