My coach always told me that people have are having 2 conversations. The first conversation is the immediate conversation and the second conversation is the hidden conversation. The latter is made up of subtle things, body language, tone of voice, etc.. In a fight, if your opponents mouth is hanging open the hidden conversation is "I'm tired." If he is closing his eyes everything you exchange, the hidden conversation is "I'm scared." The following is a guideline of hidden conversations atheists have.
1. "There's no proof God exists," translates to "I don't know what the word proof means."
2. "There's no evidence God exists," translates to "I don't know what the word evidence means."
3. "There's no good evidence God exists," translates to "My definition of good(or the definitions I agree with) supersedes all other definitions of good," or "I don't know that good evidence is relative to the person viewing the evidence."
4. "There's contradictions in the Bible," translates to "I don't know what a contradiction is."
It's funny how accurately you can discern what an atheist doesn't know from the things they claim to know.
