If you say that you would believe that the creator exists if certain changes were made to satisfy your ideas of how things should be done is simply rather arrogant.
Who are you that the creator should have to explain himself or answer to you ? You are subject to the creator it's not the other way around and beings with far greater intellect than yours have fallen for this.
Christians love you and are praying for you and even if you don't feel the same way about us. The creator of the universe waits for you. Nothing is sweeter to him than the heart of a repentant sinner. God's existance is real, suit up and get in the game.
