What planted the seed?

[Shell B]

I was raised in a non-religious household. My mom is Christian and my dad is an atheist, but neither really talked about it. I don't know if any seeds were planted. I do not remember a time when I believed the Bible or in god. I do remember going to Sunday school occasionally with a friend of mine when I was little and just sitting there uncomfortably. Perhaps that sense of awkwardness about religion was what compelled me to really form an opinion about god later in life.
