An interesting question, which I'm afraid I can't answer at this time unless I have more data from you, or from other atheists.(It's a personal question, you see.)
I don't know you in real life, and I don't know how you were raised and taught. If I met you, I could probably make a far better assessment of these things than Ican through the internet, and if we were real life friends, probably even better.
Given this information first-hand, from you, would be helpful in discerning where you are different and why.
What experiences made you atheist? What experiences led you to believe that atheism is the correct view-point? Furthermore, what experiences led you to believe the way you do about the world itself, and how do you judge these experiences to be accurate?
This is probably the biggest stepping stone to discerning where you are different and why you came to the conclusion that you did.
