Well yes, statistically a child will believe in whatever god, prophet or deity you teach him. 80% do stay in that belief system for life.I believe it would be wonderful! If you teach a child while young about God, He may stray but will always return back to him. It would teach the kids right from wrong to have faith and never give up and to always love one another.
Now does this mean the god(s) are real? Nope.
One can be taught to do good without a god.
