Okay, Atheists claim that there is no God. They know this, or believe this.
Okay now lets follow this through.
1. To claim that you know that there is not God insinuates that you have the knowledge that he doesn't exist.
2. Therefore you must have access to all information.
3. Therefore you are omniscient.
4. Which going off our definitions of a God and the one that Atheists use to disprove God via paradoxs. You are now a God.
5. But by you being able to say that there is no God, means that you exist.
6. But then as stated in 3 you are a God, yet here you are existing.
This is not an attack, I am just trying to work out the logic.
