"Since all naturalistic explanations are impossible, then no naturalistic explanation can account for their testimony."

They lied.

Also, the argument that Atheists (and everyone but the right type of Christian) send themselves to hell is absolutely rediculous. Here is a simple analogy. Someone points a gun at you, threatening to shoot you and demands all of your money. You decline, and get shot and die. By your logic they committed suicide. Lets change the senario a bit... God is threatening me (an Atheist) with hell, demanding that I believe and worship him. Do I really send myself to hell? just as they killed themselves?
