@CA, i don't know, ask one of hos followers (there are about six million in over 100 countries today).
I can tell you it includes fulfilling prophecy, and revelations from god, the same sort of thing which was claimed above for Jesus, and it doesn't in any way question your beliefs, it merely adds one (or a few) prophet/revelation.
Of course i am a skeptic. And while my faith in pantheism is imshakable - akd this unscientific; i appreciate the beaity and simplicity of the Baha'i faith and belief in unity of all world religions. Because i too believe in a kind of unity, all of the Universe as the one and only true God. Yet i don't concern myself with such details as the reserection of Jesus or the revelations of any other prophet.
I only concern myself with the practical effect of following the teachings, so if the Buddha, or Jesus, or Bahá'u'lláh have a message i see as worth following, it will listen to it. Rather than needing to assume they are inspired by a revelation from God. We are all parts of the Universe, everything we do is this in some way holy, and so i don't see the poont in arguing the toss over which religious leader has more evidence for or against them. None of them are any more 'the literal son of god' than I am, or than you are.
Hopefully that gives you an understanding of where i'm actually coming from. All humans are capable of great deeds. And it is for us to evaluate them not blindly follow.
