Whatever this guy thinks he can do, I am sure he won't be able to make humans live forever, or even "get his father back to life". Maybe he can make a machine that lives forever, but he can't make a human to live forever. There are things that god forced in this world, and it will continue regardless if you believe in god or not. And I think that god forced humans to die, and this won't change in the future.
Well one can always ask just how long did god intend humans to live? Was it 30, 60, 90, 120, 150 or 180 yrs? I think well see all of those as possible answers, given the advance of medicine and engineering. If by god you mean "stochastic calculus".. then yes, I do believe in god, and he has mysterious ways indeed :]
Well, advance of medicine and engineering?
Did medicine help prevent people die at age 5 or 6 yrs old? There is something called "fate", and I guess you don't believe in it too.
