Congratulations, and nice to have you here - I was around 13-14 as well when I finally decided that religion with personal gods is hokum. I didn't have the religious family you have, so that insight was largely inconsequential for anything...
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
