"I can go around my neighborhood and find people who can tell me about specific prayers they have had answered. I have shared that experience on these threads myself."

Not evidence. Merely claims made by people who actually said prayers hoping to get them answered. Your only "evidence" is that they're friends of yours whom you consider to be nice people, so you'd rather believe them than not believe them. They are biased (or deluded, or lying, or just got lucky). Go round your neighbourhood and find people who have had specific prayers NOT answered. I bet you never ask. Your sharing your experience doesn't mean we have to believe you. You're biased. It isn't evidence without corroboration. It's just claims. You can only give us uncheckable claims. Tell you what. Show us someone with one leg who went to Lourdes, prayed for a new leg and grew one. Now that's what I'd call evidence. Sadly...

As for three billion believing, well you need to provide accurate, checkable stats on that. In any case, three billion believing (as you claim) still leaves over three billion not believing. I won't even bother showing you where that argument goes.
