If science were to show how resurrection were possible, you would be jumping up and down on the side of science, no?
Actually, science already *has* shown that. There are a ton of documented cases of people, even in this day and age, who were thought dead but had that "fact" improperly verified (instead, they were deeply unconscious due to injury or other factor) who then subsequently "rose from the dead" after several days, much to the shock of their mourners.
And needless to say, this was likely much more common in the days a couple thousand years ago, before stethoscopes, EEG machines, basal thermometers, etc.
Plus, people are routinely "raised from the dead" in hospitals on a daily basis, via CPR, defibrillator, and so on.
Finally, even if one accepts the story about finding Christ walking around a few days after he had been nailed to the cross (and as we know, the written accounts are second-hand at best), there is *no* evidence offerred that he had ever actually been properly declared dead in the first place, in a manner known today to be reliable.
There isn't even such a claim made.
You might have a point if we're talking about injury purely by arbitray means, but not execution, and especially not in the era of the Romans.
Your desire to believe what you want impedes your ability for rational thought, at least in this instance.
