In the modern educational system we are teaching many or most children there is a God or gods, but if God does not exist, then we are misleading children all around the world.
In the meantime, the Earth is continually becoming a more endangered planet and our ability as a species to face the truth about the existence of God may be the difference between us destroying this planets environment or protecting it for future generations.
It often takes courage to face the truth but honesty is a great virtue which should be encouraged and treasured by us all.
