I find myself flopping between the two camps in a Devil's advocate manner - the evidence really isn't strong on either side. There seems to be many questions raised by NDE's, but seeing as we don't even have a firm grasp on what consciousness is, or where it comes from, to suddenly say "NDE's prove an afterlife, we can maintain consciousness when we're dead" is a very tenuous claim.
Until we can say "This is consciousness, this is where it comes from, this is what we believe to be the main contributors" to make a leap of this magnitude concerning a topic we know little about is simply irresponsible.
