I stopped arguing with atheists because they always demand evidence then dismiss the evidence. Here is an example of what I have said:
The Bible never said anything about the earth being the enter of the universe, so blaming religion is not the right thing to do. Blame those Christians.
And I'm just going by my Bible right here when I say that I am not going to argue with you because you are not willing to learn.
And finally, you will know if your atheism is fact. You say Jesus didn't die on the cross. You weren't there. You say God didn't make the universe. You weren't there. You say we evolved from some monkey men. You weren't there.
You weren't there, just like we weren't there.
Just like I will never know for certain if these perfectly timed lessons in life, dreams, and success aren't from Jesus, you will never know for certain that there is no God. But I am going to keep my faith
no matter what and you cannot stop me, just like I cannot stop you. We will see whose right in the end. But for now, I'm not going to argue with you or give you any evidence, because you will just dismiss it, saying it's not evidence, like every single atheist does. You have your mind made up, and I am not going to change it or even try to.
Enjoy.
Edit
"Just like I will never know for certain if these perfectly timed lessons in life, dreams, and success aren't from Jesus" That was sarcasm.
