Many christian denominations truly believe that Jesus is God. Some believe in the trinity, others believe that he is/was the son of God, without the holy ghost. Almost all the southern Baptist types believe that in order to be admitted to heaven the individual must swear an oath that "Jesus is my lord and savior". So for southern Baptists, Jesus is God.
The salient question is whether the Jesus of the Christian bible ever actually existed. If he did exist was he merely an ancient con man or was he the son of God or even God himself in earthly disguise? Was Paul just making up a lot of fairy tales when he did the super sales job on behalf of the real or invented Jesus person? Which Jesus? At that time the name "Jesus" was a common one. Which of the many are we to be persuaded (or conned) to worship? Along about that time another magic man named Appolonius was doing more miraculous stuff than the biblical Jesus person. He was far more educated, more widely traveled, a superior magician, and a skilled orator. He doesn't get any mention at all in the Christian scriptures. Maybe he was the son of God and the ancients got their names and characters mixed up.
