Recently, I've seem some atheists post this flowchart as an indictment on theists' ability to discuss religion. You need not look far to see where most theists fail in this chart. In fact, it needs not "flow" anywhere. The first statement is: Can you envision anything that will change your mind on this topic?
Religious faith, by definition, makes the answer to this question no. If you have doubt, then you don't have faith. How different are atheists? We hang our worldview on critical thinking and the lack of compelling evidence and leave faith out in the cold. I am very certain that atheism is currently the wisest position. Still, we should ask ourselves what kind of evidence would be needed to change this.
Extraordinary claims require extraordinary proof. ~ Marcello Truzzi
Extraordinary claims require extraordinary evidence. ~ Carl Sagan
The weight of evidence for an extraordinary claim must be proportioned to its strangeness. ~ Pierre-Simon Laplace
In my recent interview series, you may have noticed that I'm consistently asking the question "Is there anything that would convince you that there is a god?" The answers can be paraphrased as "barely." A believer might think that Jesus returning would immediately bring all the infidels into the Christian fold. Not so much. The general consensus is that, atheists would remain skeptical. This new Jesus would be subjected to the scientific questions posed to all supposed evidence. Is he authentic? Are his miracles more than tricks and illusions? Does he provide some wisdom that could only come from God? Some of us go so far to posit he could be the product of other worldly technology.
Any sufficiently advanced technology is indistinguishable from magic. ~ Arthur C. ClarkeNevertheless, I would at least consider a magical Jesus in the real world is authentic, but it wouldn't get me speaking in tongues as fast as some other extremely unlikely scenarios. Below is a chart of events that would make a believer out of me. I used Dawkin's Scale of belief to show what degree of belief I would hold for each event. This is an approximation because each event could be more or less convincing depending on the circumstances. Of course, combining events would also hasten my conversion. For example, a previously dead religious figure performing a large-scale miracle with witnesses might seal the religious deal.
