No offense ruff-n-tuff but it appears you have no idea what being an Atheist is or even it's definition. I'm unsure weather to even take your question seriously. You are not an Atheist and you don't "try Athesim out". I would respectfully suggest you search inside yourself for what you believe to be logical and rational and you will have your answer. You claim to believe in god and love god so you are not an Athesist, you can not have both.
