[ QUOTE ]
Atheism and Agnostism are mutually exclusive. Atheism is a belief: a belief that there is no higher power. Agnosticism is a belief: a belief that a person cannot know if there is a higher power or not. You can't both definitively state that x does or does not exist and then say that it is impossible to know whether x exists or not. The two statements are mutually exclusive.

You sound home schooled so you may not have been exposed to some outside concepts - consider that you were born an atheist ( you didn't believe in Thor, Allah, Yawah, toothfairy ...) and it had nothing to do with you proving they didn't exist. You simply started out not believing and then changed over time as evidence arose .. tooth fairy being your first conversion.
The others lack such evidence so some never take them on.
