This questions comes up now again on atheist blogs. Jerry Coyne, to my knowledge, has asked it at least twice, with the further caveat that he claims he never gets an answer. I answered twice, and neither time did he publish my response, so his claim remains, in appearances only, valid.
This question arises on atheist blogs usually coupled with an explicit presupposition, that seems to be important to internet atheists, that nothing could shake the blind faith of a believer, because we’ve all drunk the kool-aid.
I will tell you what I think would make me lose my faith. There are two things that come to mind. One is the incontrovertible evidence (let’s use the current 5-sigma standard) of a parallel universe, especially one with different physics. The other is the detection of intelligent aliens who have no concept of God.
It is funny when you give this answer on an atheist blog and, unlike on WEIT, it actually gets out of moderation. Atheists will begin to argue with you that no, it would surely not cause you to lose your faith. They might say: “Why should that make you lose your faith, couldn’t your god create many parallel universes and create alien races?” The answer “Well, yes I suppose he could, but I didn’t arrive at my faith by rational reasoning and I wouldn’t necessarily lose it through a rational process, but simply reach a point where, in the face of complicating discoveries, where I no longer believe.” Another approach I have seen is where they simply declare that I am lying.
Has anyone had a similar experience?
