Just to recap...the theory was that Jesus had learned the arts of sleight of hand and conjuring at the hands of travelling street magicians in Egypt (where Jesus apparently spent quite a lot of his formative years) called Gali Gali men.
As we all know, practicaly all the well known miracles can be re-created by illusionists and made to look real, because modern day magicians do them all the time.
Even coming back from the dead. (Voodoo priests will actualy poison someone with something called tetrodotoxin. This drug puts a person into a coma that resembles death. The victim retains full awareness as he/she is taken to the hospital, then perhaps to the morgue and finally buried in a grave. The voodoo priest or 'bokor' then raises the victim and administers a hallucinogenic concoction, called the "zombi's cucumber," that revives the victim. Once the victim has been revived, he/she has no power of speech, their past human personality is entirely absent, and the memory is gone, probably because of the strong hallucinogens used in this Voodoo practice, which are probably administered again and again to keep the victim in this state. The victim is then called a 'zombie' and used as a slave by the voodoo priest.)
So why couldn't the original miracals have been done in a similar way to how a modern magician would do them? We know conjurers and magicians existed at the time with knowledge that could make 'miracles' look real.
The interesting thing about the walking on water miracle is that it was only witnessed by those that Jesus chose to surround himself with, his desciples. If Jesus was indeed a conjurer rather than the actual earthly embodiment of God, he would need helpers, just as any stage magician does. If this was the case, then the obvious suspects for being Jesus's 'stage hands' would have to be his desciples. So it's not going beyond the relms of possibility to postulate that the walking on water miracle might well have been a pure fabrication in order to promote Jesus.
