If you research Horus independently without references to Jesus, I think it's fair to say there is little to justify making direct comparisons between the two. However it is not possible to make the case that early Christians had something unique, or that they would somehow not have been influenced by a lot of comparative mythology in which they would have been culturally immersed. Indeed, it is unarguable Christianity started out as a very small Jewish Sect which of course carried with it long and ancient histories of myth making and story telling. There are parts of the Old Testament whose stories exist at the beginnings of human civilization and of which religions had lasted thousands of years upon. Judaism evolved through older religions just as Christianity's evolution through Judaism. There are nevertheless many Pagan, Greek , Roman Gods predating Jesus with similar tales and ritual. The common connection through them all from Osiris to Horus to Yahweh to Jesus to Jehovah, is perhaps not a literal similarity with each other, although there is quite a lot, but the way in which all of their mythical states are each allowed to transform into false reality for a period of time solely through the fertile ground of human imagination. There is Osiris who brings to his believers eternal life. Considered mythical. Romulus the Son of God, born of a virgin. Considered mythical Dionysus the Son of God, born of a mortal woman, who could turn a rock into water and the water into wine. Considered mythical Apollonius of Tyana who could heal the sick, cast out demons, and raise the dead. Considered mythical. The Sumerian Goddess Inanna who was crucified and resurrected from the dead. Considered mythical. Then follows Jesus the Son of God, who can bring eternal life, born of a mortal virgin woman, who could turn water into wine , could heal the sick, cast out demons and raise the dead , who was crucified and resurrected from the dead. somehow.... Considered NOT mythical. http://folknation.wikia.com/wiki/Comparative_mythology The Flood Template:Main article Cultures around the world tell stories about a great flood.[14] In many cases, the flood leaves only one survivor or group of survivors. For example, both the Hebrew Bible and the Babylonian Epic of Gilgamesh tell of a global flood that wiped out humanity and of a man who saved the earth's species by taking them aboard a boat.[15] Similar stories of a single flood survivor appear in Hindu mythology,[16] Aztec mythology,[17] and the Greek myth of Deucalion. The creative sacrifice Many cultures have stories about divine figures whose death creates an essential part of reality.[18] These myths seem especially common among cultures that grow crops, particularly tubers.[19] One such myth from New Guinea tells of a miraculously-conceived girl named Hainuwele, whose murdered corpse sprouts into the people's staple food crops.[20] The Chinese myth of Pangu,[21] the Vedic myth of Purusha[22], and the Norse myth of Ymir all tell of a cosmic giant who is killed to create the world.[23]
