Considering most people don't live after three days without water, yes, and the fact that they still had the strength to pray and sing. And on those accounts, the Romans confirmed there was a person called Jess Christ with a following, and he Jewish account, written by Josephus if I remember correctly, said there was a Jesus Christ and that he did do miraculous works. Also, rember that these are not Christians confirming this, these are people of groups opposing Christ and His followers, so there it would be hard to find any "Enquirer" factor of made up or exagerated information unless the original documents were tampered with later on. Also, if Jesus was not divine, the crucification story kind of falls apart, for a person doesn't gain such a following simply by preaching and that one of the main reasons the Saudecees and Pharisees wanted to see Jesus crucified was to see if he could escape his own death, so he had to have done some amazing works to make these people think he could do this.
Also forgot to include the miracles at Lourdes and Majegorie(sp?).
