Extraordinary claims demand extraordinary evidence.
What independent and verified evidence can you provide to prove that jesus was indeed resurrected. Belief and faith are not evidence.
The four gospels are not eyewitnes accounts as they were written by unknown authors and decades after the so called events. Paul was not a eyewitnes of the resurrection.
So eyewitness accounts that lived at the time of the resurrection and that can be verified eg Jewish Greek and Roman historians.
