Well lets look at your "verifiable claims"
"He was born in Bethlehem."
How would you verify that ? Especially when you don't know when he was supposedly born, if it was under local rule or Roman. (I personally beleive this to be false - Jesus was more likely born in Galilee)
"He preached sermons to thousands."
How would you verify that ? Perhaps by produvcing witnesses. Well were witnesses produced ? Was it ever verified ? (I personally believe Jesus' preaching to be exaggerated there's not much record of his preaching in non-Christian sources)
"He healed people, gave sight to the blind."
Standard stories about faith healers. How could that be verified and is there any record that it was ? (I don;'t beleive that one either).
"He was crucified."
Probably true but was it ever verified ?
"He was buried."
Probably - although there's a good chance it was in a common grave and not a tomb. How woudl you verify that ? Today you could maybe dig up mass graves and DNA test all the remains but not back then.
"That he was raised from the dead and seen by hundreds of other people."
Except that the "hundreds of people" don't seem to appear in any of the Gospels or in Acts. If it refers to an actual event it is likely just a vision. And how would you verify that he had been literally raised ?
