Our reasons for believing Jesus existed and also that He was who He claimed to be - the God who came down - are the same reasons for believing any fact of history: the documentation is substantial and it passes all the tests of historical reliability. Scholars - both liberal and conservative - overwhelming agree that Jesus of Nazareth was a man of history and the Gospels, on the main, tell His story accurately.
Always make it a goal to keep your conversations cordial. Sometimes that will not be possible. If a principled, charitable expression of your ideas makes someone mad, there’s little you can do about it. Jesus’ teaching made some people furious. Just make sure it’s your ideas that offend and not you, that your beliefs cause the dispute and not your behavior.
Why so many mentions regarding Jesus from such a wide variety of sources (Pliny, Tacitus, Lucian, Josephus, to name a few)? Because Jesus of Nazareth was a man of history, who made a profound impact on history. There's no good reason to doubt that Jesus existed, or to think the real Jesus was completely different from the one depicted in the Story.
If the Christian doesn't get reality right, he loses effectiveness in this life. If the non-Christian doesn't get reality right, he loses much in this life, and everything and the next one. As Jesus put it, "What does it profit a man if he gains the whole world and loses his soul?"
Christianity is actually "true Truth," as Francis Schaeffer used to put it. God really does exist, Heaven actually is real (along with Hell), Jesus really did live and He did the things the historical records - the Gospels - say He did, the resurrection of Christ really happened, and there really is hope each of us can count on for "the kind of perfect world our hearts have always longed for."
Most Christians who've been around for a while have their Story in bits and pieces, but have never seen how powerful it really is when assembled as a whole. I want them to see how well it fits together and how it offers tremendous explanatory power regarding the world as we actually find it. I want them to see how it resolves the problem of evil, and why God's solution - the God/man Jesus - is the only solution.
The word "Christian" means something in particular. The basic outline and general truths and doctrines central to Christianity have been hammered out over 2000 years of reflection on the teachings of Jesus and his apostles. If you disagree with these foundational concerns - the kinds of things I focus on in The Story of Reality - then you're simply not a Christian.
