its not that complicated
atheists i've known believe in everything everyone around them believes
do all the same things, conform, obey society, everything
except they dont go to church
thats seriously it
most christians are nearly atheists too, they have no idea what they believe, just what their parents and grandparents believed
church is a social event in america, they have football games and food
prayer is not a part of their lives
some dont even go to church, dont pray, never read the bible, and still call themselves christian
