The Mystery of Jesus' Unconscious Death

There are so many explanations for the resurrection of Jesus that even atheists don't agree. But we're going to go through all of them in rocket speed tonight. Maybe they were just wrong and Jesus wasn't dead at all. He looks like he's dead. Therefore, when they pull him off the cross and they bring him back to life, it's just a resuscitation. It's not a resurrection. How do we know he's really dead? I can see just kind of looking at the biblical evidence how people could doubt that he's died.
