Challenge to atheists: I find your lack of faith disturbing!

[The Reality Salesman01]

Of course somebody could believe something that is untrue.

I appreciate your honesty. Now that we have found common ground, please allow me to bother you with one more question, and it is my hope that you do so with the same sincerity.

If somebody believes something that is not true, what would it take to convince them to change their mind? More specifically, what evidence would convince you that your belief is wrong?

If your belief is supported by evidence, then it follows that there’s a possibility of some new evidence that could make it more likely false. This is true with all evidence based claims.

If somebody is delusional, no amount of evidence would convince them that they were mistaken. You would be right to ask me the same question pertaining to what I would require in order to believe, and I am prepared to answer it. But as a sign of sincerity and intellectual honesty, oblige me with your answer, and I will be happy to return the sentiment.
