Jesus is copied from pagan myths like Horus, Mithras, and Dionysus.

When you check the primary sources, the parallels evaporate. (1) Horus was not born of a virgin (Isis conceived via a reconstructed Osiris), not born on December 25, had no twelve disciples, was not crucified, and was not resurrected in anything like the Christian sense - these claims come from 19th-century occultist Gerald Massey and the 2007 film Zeitgeist, not Egyptology. (2) Mithras was born from a rock, not a virgin; the bull-slaying iconography appears in Roman Mithraism, which postdates Christianity by decades. (3) Dionysus myths of dismemberment-and-return are quite different from a historical public execution followed by bodily resurrection witnessed by named contemporaries. (4) More fundamentally, 1st-century Palestinian Judaism - the matrix of earliest Christianity - was ferociously allergic to pagan syncretism; the earliest Christians were Jews who risked martyrdom rather than offer a pinch of incense to Caesar. (5) The resurrection of Jesus is not a seasonal nature myth but a specific, datable, named claim about a Galilean rabbi executed under Pontius Pilate, proclaimed by eyewitnesses in the same city where the tomb was. N.T. Wright (The Resurrection of the Son of God, 2003, ~800 pages) shows there is no Jewish or pagan analogue to what the first Christians claimed.
