I think you fundamentally don't understand what Christianity is about. Hint - it isn't about transforming this world into perfection.
I disagree with your underlying premise that it takes indoctrination to believe in God. Every culture has come up with its own version. Humans are hardwired and if they don't find God, they create idols. I was from a nonreligious home but loved God from early childhood (preschool). I can't remember not feeling his presence in my life. I consider it a gift. Please don't discount what you don't understand.
