I think agnosticism is an apt description for how a human is born - virtually clueless to any sort of knowledge.
Then we grow up, be exposed to the various proposed gods and supernatural claims, and the rational sceptics among us simply reject belief in such conceptions and claims i.e. atheism.
I think the default position is animist. I remember taking revenge on inanimate things (like a door handle that was in the way) as a kid. Hell, even today I want to take a hammer and smash the table if I kicked it with my little toe before I had any coffee. Anyway that is my position.
I have my opinion and you have yours.
Do you care to explain why you believe people are born Muslims? Is it because everything submits to Allah's will and only humans have a free will to rebel? So a baby has not learned to use his/her free will yet, thus submits to Allah? Is that the thinking?
I think it's quite easy for a rock to be Muslim (submit to Allah's will). Here's how I imagine it works:
Allah to rock: oh rock, stay and don't move unless someone moves you!
Rock: I hear an obey, I will stay still, o Allah and I will not move. I am a Muslim.
Well, it's easy for a rock to just stay still, because it can not do anything, dammit.
Do you agree with this analysis, Aba Abdillah? Do rocks obey Allah, according to the Koran?
