Note that Herculean myth resembles Jesus in many areas. The mortal and chaste Alcmene, the mother of Hercules, gave birth to him from a union with God (Zeus). Similar to Herod who wanted to kill Jesus, Hera wanted to kill Hercules. Like Jesus, Hercules traveled the earth as a mortal helping mankind and performed miraculous deeds. Similar to Jesus who died and rose to heaven, Hercules died, rose to Mt. Olympus and became a god. Hercules gives example of perhaps the most popular hero in Ancient Greece and Rome. They believed that he actually lived, told stories about him, worshiped him, and dedicated temples to him.
Likewise the "evidence" of Hercules closely parallels that of Jesus. We have historical people like Hesiod and Plato who mention Hercules in their writings. Similar to the way the gospels tell a narrative story of Jesus, so do we have the epic stories of Homer who depict the life of Hercules. Aesop tells stories and quotes the words of Hercules. Just as we have a brief mention of Jesus by Joesphus in his Antiquities, Joesphus also mentions Hercules (more times than Jesus), in the very same work (see: 1.15; 8.5.3; 10.11.1). Just as Tacitus mentions a Christus, so does he also mention Hercules many times in his Annals. And most importantly, just as we have no artifacts, writings or eyewitnesses about Hercules, we also have nothing about Jesus. All information about Hercules and Jesus comes from stories, beliefs, and hearsay. Should we then believe in a historical Hercules, simply because ancient historians mention him and that we have stories and beliefs about him? Of course not, and the same must apply to Jesus if we wish to hold any consistency to historicity.
And while we're at it
the religion of Zoroaster, founded circa 628-551 B.C.E. in ancient Persia, roused mankind in the need for hating a devil, the belief of a paradise, last judgment and resurrection of the dead. Mithraism, an offshoot of Zoroastrianism probably influenced early Christianity. The Magi described in the New Testament appears as Zoroastrian priests. Note the word "paradise" came from the Persian pairidaeza.
The Egyptian mythical Horus, god of light and goodness has many parallels to Jesus. [Leedom, Massey] For some examples:
Horus and the Father as one
Horus, the Father seen in the Son
Horus, light of the world, represented by the symbolical eye, the sign of salvation.
Horus served the way, the truth, the life by name and in person
Horus baptized with water by Anup (Jesus baptized with water by John)
Horus the Good Shepherd
Horus as the Lamb (Jesus as the Lamb)
Horus as the Lion (Jesus as the Lion)
Horus identified with the Tat Cross (Jesus with the cross)
The trinity of Atum the Father, Horus the Son, Ra the Holy Spirit
Horus the avenger (Jesus who brings the sword)
Horus the afflicted one
Horus as life eternal
Twelve followers of Horus as Har-Khutti (Jesus' 12 disciples)
But of course those are myths, and the story of Jesus is true. Yeah, sure.
