How about naming just three of them. Even if there was any evidence of them, why is JEsus Christ set apart from all the others?
Krishna, Sakia, Thammuz, Wittoba, Iao, Hesus, Quexalcote, Quirinus, Prometheus, Thulis, Indra, Alcestos, Atys, Crite, Bali, Mithra -- all share similarities to the Christian story. There are others sharing most of the elements, but I don't have time at the moment to research them.
What sets Christianity apart is the conversion on Constantine.
