Acts17apologetics find new evidence; Resurrected Jesus appears to his enemies?

In answer to the video "Paul Won Converts Through Peaceful Preaching; Muhammad Used Bribes and Threats (PvM 17)"

As Paul candidly admits,

1Corin15:17"If Christ has not been raised, your faith is futile and you are still in your sins".

In essence, the validity of Christianity stands or falls on this claim. Yet the admittedly crucial nature of that event is contrasted by the scarcity of material related to it within the Gospels. Barely 5 people witnessed the risen Jesus, and when analyzed critically, these testimonies are contradictory and inconsistent.

In Mark, Matthew and Luke, Jesus' message is centred not on the resurrection, but on the establishment of God's kingdom on earth, a metonym in those days for God's rule of justice and restauration of JEwish glory among the nations, with the defeat of the Romans. It is only with the development of Christology with John's Gospel and Paul's writings, as well as the Greek Church fathers, their rich Hellenistic background of mythologies and legends of deified leaders, that supplied the fertile ground for the short story of Jesus' resurrection, his interpolated deification. This Hellenistic perspective however isnt on par with the Jewish background which the writers and early Christian scholars claim provide proof for their beliefs on Jesus.

In Jewish understanding, the resurrection of the dead is a common theme that has already occured in the past and that shall happen again in the messianic era, without any divine connotation or connection with atonement for sins. These men were formulating their ideas, interpreting inherited traditions while still infused with stories of demigods, Achilles, Dionysus or Heracles to name but a few. By the time they expressed their thoughts and the Gospels were put to writing, the Jerusalem Temple had been destroyed in 70CE, and the centers of Christian thought were spread around the Mediterranean. This opened the way for non-Jews and foreigners to Jesus' socio/cultural/religious background to take the reigns of power in the early church.

When challenged by the Pharisees to display a miracle, Jesus promised them his resurrection after being dead for 3 days Matt12:39. Once he is supposedly resurrected, he doesnt appear to those who specifically asked him for the sign and to whom he said he will reappear. Instead, Jesus' followers come to the Pharisees, claiming that the sign had occured. Neither is there any claim that the risen Jesus ever appeared to anyone but believers. There is only the word of a mere handful of "witnesses" whose stories vary from person to person, and we dont even know who transmitted those biased accounts until they were eventually put to writing by scribes whom nobody knows.
