I don't believe in God because of the impossibility to prove/disprove a certain God. I can easily state that, quoting Vbraun, that the universe and all of it's entity was created in a supernatural toilet flush, and you can not possibly disprove that.
Also, most people trying to convert me to Christianity use the argument that:
God does not exist
Athiests and Chirstians lose.
God exists
Athiests lose, and Christians win.
But, if God exists (not in the form that Christians want), but prefer people to believe in no God, over worshiping a false God (Christianity), then Christians lose, Athiests win.
It's not just Christianity or Athieism, but it can be Christianity, Atheism, Islam, Hinduism, Bhuddism, Indiginous Minor Religions, Greek Polytheism, Judaism, Scientology, Vbraun's Toilet Flushism, Alien Religions, or even that no one in the universe has gotten the correct religion.
