Well, I think there's more evidence than you're listing. First of all, the body was indeed missing because if it wasn't, the authorities could have ended Christianity before it had even begun by producing the body. So they didn't have it. Secondly, Jesus Himself, claimed he was going to rise from the dead, so even if you don't believe in Jesus, He was either deliberately lying or He was a lunatic (if He didn't rise from the dead) which would disqualify Him from being a "good teacher" that a lot of people like to call Him. So there aren't a whole lot of options left. He either wasn't dead when they took Him down, which is the least plausible scenario or the disciples stole the body. So the disciples; scattered, afraid for their lives, literally in hiding, come up with a crazy plan to tiptoe past a whole gang of Roman soldiers who (knowing it was an immediate death sentence to fall asleep while on duty) SIMULTANEOUSLY fall asleep. The disciples (most of them were probably necessary for this next step) put their shoulders into a boulder blocking the entrance to the tomb that is estimated to have weighed in the neighborhood of 4,000 LBS. Breaking the Roman seal on the tomb (another crime punishable by death) to again tiptoe past the sleeping guards (obviously exhausted since the heave-ho on a 2-ton boulder didn't wake them up) to spirit Jesus' body away. Lastly, and in some ways most importantly, the disciples weren't just ready and willing to die for Jesus as you put it. They DID die for Jesus, all of them with the exception of John. They were all martyred. But think about that for a second. They died for something they absolutely knew, without question, was a lie. If Jesus hadn't risen (liked He claimed He would) then everything Jesus had told the disciples was a lie. Would you honestly die for something you absolutely knew was a lie. I wouldn't. I don't think you would....I don't think the disciples would either. Half of these guys were hardened fishermen. Think New York Dockworker and you get a pretty good picture. Salt of the earth type of guys. No nonsense guys. Guys who would not very likely choose an early death for no benefit to perpetuate something they knew was a lie.
Does this prove Jesus rose from the dead? Of course not because without faith it's impossible to please God. But when you stop looking at any one thing, and you look at everything as a whole of what would have had to have happened for the resurrection to be fake, it's pretty compelling. I think there is way more evidence to support Christ's resurrection from the dead than to prove Bigfoot is real....and that's from someone who LOVES Bigfoot.
