What Scriptural Proof for the Papacy?

What scriptural proof for the papacy? Would doctor walls accept in scripture if not for jesus renaming peter to chathos, giving him the keys to the church and heaven backed ty? Well, i meant those passages have alternative interpretations. And a protestant biblical authority shave no pro whatever, making perfectly good sense of what jesus is saying without buying the roman catholic line. So i would like some clear, some clear evidence that pPeter was, in fact, the first pope.
