Yup. I'm using the recently devised definition of
@durangodawood in another thread when he said:
"An extraordinary claim is one that, if true, requires one to reframe your whole outlook on life. Or one that demands a revolution of the common understanding of how the world works."
So, for a non-believer, the resurrection is an extraordinary claim because it would require them to change their whole outlook on life. Extraordinary claims require a greater body of evidence because you want to be certain that the claim is correct before you change your world view.
Because the claim is not extraordinary, little evidence is necessary to reasonably believe it could have happened.
For example, if someone tells you that they fart butterflies in the morning and show you a picture of it, I'm pretty sure you're going to seriously scrutinize that photo for photo-shopping.
If someone tells you that they eat Cheerios in the morning and show you a picture of it, you probably won't scrutinize the picture for more than an instant, nor would you be suspicious that it is photo-shopping and he
really was eating Shreddies.
Why? Because, if someone can fart butterflies, then that changes many things that you know and understand about human anatomy, butterflies, etc. However, someone eating Shreddies instead of Cheerios is pretty irrelevant to your worldview and so doesn't require more than a simple photo (or even just word of mouth) to be believed.
Because it is extraordinary. People don't wake up and start walking around 3 days after they had died. If such a thing happened, it is extraordinary and would require a re-working of my worldview. Because of this, I treat the claim with more scrutiny than I would other claims. For example, the claim that Jesus was crucified does not require a re-working of my worldview; crucifixion was a common form of execution in the Roman empire and would not be out of the ordinary at all.
I would like to answer these questions, but I believe they belong in a different thread. This thread is talking about whether or not the historical Jesus existed,
not whether he was divine/God/saviour/zombie.
