Atheism is essentially the belief that in the beginning there was nothing, and nothing was something, and nothing created something.
An alternative cope could also be that atheism is the belief that there never was a beginning (contradicting the Big Bang theory), thus the Universe is eternal, was caused and is sustained by itself, contradicting the laws of physics and logic.
Another possible definition of atheism is the belief that some Jews made up a fake story that would get them excommunicated, persecuted, killed and then went and died for it. Or that the Roman Empire created a religion that went against their way of life, persecuted it for three centuries and then made it the official religion of the empire.
You don't know the history of Christianity, you are philosophically illiterate, you believe that the Universe created itself from nothing, that spontaneous generation magically occured for no reason at all and that we evolved and became moral through a mindless biological process. And notice, I don't deny the Big Bang or Evolution, which are both scientific theories that were put forward by Catholics, Lemaître and Lamarck, I deny the retarded, illogical and fallacious notion that it all happened without a creator.
>MUH WHO CREATED GOD!!?!?!
Professional atheists don't use this objection against theism because it is arguably the most idiotic one.
God is outside time, he is immaterial, he is not extended in space. He is not bound by the laws of nature because he created them in the first place. An eternal creator is not bound by time, an immaterial creator can't be created.
When we say that everything that exists has a cause, we are talking in physical terms. God is not physical, the Universe is.
Anyways, why would I waste my time explaining anything to an atheist when they are ignoramuses who will believe whatever allows them to watch porn and smoke weed without being held accountable?
Stay mad, stay coping. Christ is King.
