There are any number of instances of people who have convinced large numbers of followers that they were some kind of deity. If you are Christian, you can point to Mohammed, and if you are Islamic, you can point to Jesus. Both were historical figures, although there may be more independent corroboration for Mohammad than Jesus. The fact that large religions grew up based on Jesus and Mohammad is an indication that it doesn't take a real "god" to generate such religions.
About Jesus' death and resurrection. You might look into the Zombification that's been practiced in Haiti for centuries based on a toxin from the puffer fish. The puffer is also found in the Red Sea. Jesus hung out around fishermen, and we don't have any idea what skills he learned between age 12 and 33.
It's a stretch to think that he could have used this toxin to perform his resurection miracles on others, and then on himself. But it's not out of the question either. You will note that he was taken from the cross earlier than the two thieves, after being pierced with a spear and having no reaction. That is exactly the symptom of puffer fish Tetrodotoxin poisoning. Removing him from the cross early kept him from dying of those effects.
This is all speculation. And it's way off the subject of evolution. But the bottom line is there really is no bullet proof evidence that anything in the Bible is true. And noting the growth in beliefs of any number of other mutually exclusive religions, common sense says that Christianity is just another one of those.
This discussion about whether God is real and the Bible is true is always where discussions of evolution lead. Except with Catholics who have followed the lead of the Vatican and separated their faith from any possible conflict with science. That is the intelligent policy, and someday perhaps American fundamentalist Christians will follow it.
