Anyone who's not naive and for this reason can't be duped, anyone who's got logical and rational sense can easily deduce that in the time of Jesus there were many others like him. They also used hypnotism and performed magic tricks and healings that the gullible unschooled superstitious people of his time saw as miracles. Yet, he was brighter and had a superior ability, so he outperformed the other miracle workers. He was so bright that he shrewdly managed to lead the ignorant brutish semi-primitive people to believe he was God's son. Something he knew wasn't true, for he himself didn't believe in God. Because he was brighter than his contemporaries and, unlike them, had a rational and logic intelectuality.
