Or maybe you want a hotel log saying "peter checked in here, AD 63, signed Nero"? Tell me the proof you need other than 2000 years of oral and written history attesting to that fact, a marked grave, markings throughout the catacombs indicating his presence, and the fact that a church and/or pilmgrimage area was built almost immediately over the spot of his execution since immediately after his death?
Oh, and more importantly, I can tell you as an attorney, as you are raising the charge, the burden of persuasion and production is in your hands, not mine.
