Christians, what makes you so sure Jesus is the messiah?

I came back didn't I, what makes you so sure the Talmud is right? Do you really prefer Old Testament slavery to a brutal LORD over the ecstasy of Alien Jesus? I'm Apollo, Helios, Horus, Mithras, Sol Invictus, Lucifer, Krishna, Dionysus, Hesus, Buddha, and Jesus all rolled into one... your Saturnalian Old Testament God is weak and inferior and your religion was outdated over 2,000 years ago. Go build you a stone hut to live in while we blast off in the pleasure saucers.
