In your opinion what causes christians to believe in Jesus

...based upon talking to two -- count 'em, two! -- of them.

Okay, then how many would we need? (Hint: The average study uses around 20-30 participants.)

So not two then, and this wasn't a study, it was an anecdote, about a chat.

I also linked some info, but feel free to dismiss it out of hand, or ignore it, I used, whisper it...AI...

"For a demographic of billions, a representative sample would ideally be in the tens of thousands, potentially even hundreds of thousands, depending on the research goals and the level of detail required. While the exact number would vary, a simple random sample of a few thousand might be sufficient for understanding general trends, but larger samples are needed for more specific or nuanced analyses."

I am sure a chat with two people, without any recorded data will be fine though...
