The following argument is in response to a person proposing a proof of God he had recently discovered, finding it to be a satisfactory proof. John Loftus responds as follows:

“Is this why you believe? Surely not, because you believed before ever hearing of this argument. So tell me why you first believed. That is much more interesting to me. I want to know what brought you to believe in the first place. Which religious or non-religious options did you consider before choosing Christianity? What program of study did you follow in doing so? What works of a skeptical nature did you consider before making your choice?” – John Loftus

Merely accepting what parents, friends and family believe is not proof of anything, let alone Christianity.
