I guess it would help to first know what is life. Our brains are wonderful machines, but no machine is alive, in the sense of being aware of anything. My brain cells are no more alive than the chips of my dump computer. The fact is that we simply have no clue as to what generates our conscious existence.
So, if we don't know what life is, it's no wonder that the question of death is still keeping us busy.
The survival of our conscious existence doesn't seem to make much sense. You would have to believe that, while some moderate brain damage might send you into coma, more extensive, irreparable, damage would awaken you to extra-bodily life. Strange.
The Bible is quite confuse on the afterlife. Jesus himself mixes up a Jewish belief in a resurrection with references to the Greek belief in survival of the soul. The resulting credos are very lame (bodily/spiritual resurrection) or completely insane (hellfire in any form).
Resurrection pure and simple remains a possibility. It all depends whether there is a God to do it. If he exists, I have no doubt he'd want to set a few things straight, and resurrection would be the way. I don't know if I should continue to believe in God. The fact that he hides himself is so weird. Yet, the very existence of life testifies in his favor. So, my bet is still that there might be some resurrection possible.
