"As an atheist, wewe will occasionally meet a non-atheist who wishes to argue against your belief system. If wewe are interested in discussing the matter, wewe may want to prepare yourself kwa learning these simple responses to common anti-atheist arguments.
The Bible says that atheism is wrong.
"The Bible also says some guy's donkey talked."
