i organized my thoughts from another thread, and thought i'd share it here. i'll probably take the debate to other debate websites too, to get a feel for a wide range of opinions. i have trouble logging in so i wont be able to respond as consistently as i'd like.

dr. jeffrey long wrong a book, 'evidence of of the afterlife'. a smart and capable doctor writing a book like that should be sufficient to establish evidence, but i know some peeps are too stubborn to leave it at that.
let's look at some lines of evidence:
philosophically, it's just plain stupid to argue that it's common for people to hallucinate elaborate afterlife stories when they die. why would this even happen? drugs, dreams, and other hallucations dont cause people to hallucinate elaborate afterlife stories in any other aspect of life... why should we assume there's something special about dying that causes this?
out of body experiences are commonly verified as accurate, to the point of almost always being accurate. doctors and professionals are often some people verifying things that occurred when someone was dead, when what the dead person knew was impossible to know. if ya'll want a start in researching out of body experiences, 'evidence for the afterlife' by doctor jeffrey long does a short literature review of some highlights. there's lots of studies that look at the accuracy of those experiences and they're always shown to be accurate. there's whole scientific journals out there dedicated to this stuff, the evidence is basically too overwhelming to just ignore. even the AWARE study where they tried to measure out of body phenomenon, had two examples where someone who was dead knew what happened out of their body. and there was some measurement of auditory ability when they were dead. now, yes this isn't the level of evidence that leaves no room for doubt, and this isn't exactly being able to be measured in a lab on demand.... but this is all evidence that is being measured and can be repeated. it's basic science.
dead family members. when people experience beings on the other side, the beings met are almost always dead and almost always family members. if this was just a random hallucination, there should be many more examples of living people and people other than family members. this consistency is a strong point.
there are plenty of examples of blind people seeing when they die, often for the first time ever. the examples who people who are coming to grips with a new sense, it takes time to process and that's exactly what we see.
here is more on the NDEs of blind people
some other lines of evidence:
-another good piece of evidence is that when experiencers are surveyed, they say their 'life reviews' are always accurate, 100% of the time. if this was just a brain going hay wire, we'd expect lots of false memories.
-i think this also goes along with the idea that if this was a brain going hay wire, people would experience lots of random images, like a hallucination or dream. instead, they see lucid clear after life experiences that they have no doubt about and that are more real to them than their earthly lives.
-also, people often see images in their life review, that they've long forgotten. it's not as likely just a brain going hay wire if it's showing the whole life even the forgotten stuff.
-it's also good evidence that the same sorts of NDEs happen to people who have never heard of these experiences, and to children who are too young to know about it either.
-it's also good evidence, that across all cultures, the themes in the experiences happen the same. that is, tunnels, light being, life reviews and such... all these things happen at the same rate regardless of country or culture. i realize humans are similar, so the argument that we just have similar experiences is possible. but if this just a brain going hay wire, it wouldn't be so consistent and would be a lot more like random images or random experiences.
more on consistency.
-almost every person who has these experiences after the exerperience then believes in the afterlife. if these were just hallucaionations, you'd expect this not to so consistent.
-it's also worth noting, that a majority of atheists even come back believing in God... it's almost never the case that theists end up becoming atheists. the atheists who dont convert, just had no special insight on the matter, the ones who gain knowledge of something end up becoming believers. (this is also a line of evidence for the existence of God)
-it's very rare to find a non christian religion NDEs by the way. the experiences are so rare, that i challenge anyone to find just a few of them. the only ones i've seen are too open to interpretation to draw too many conclusions from.
the skeptic arguments against NDEs being authentic are at best hunches, it lacks specificity in science. there's no known afterlife gene or something in our brain that we know of that would cause this. yes, we are all similar so maybe our survial gene is facilitating all this. but like i said, it's all just a big hunch. we have lots of science and scant evidence to support skeptics. there's simply not enough evidence to be a skeptic about whether there is even evidence to begin with. this is all evidence, so skeptics have a repubuttable presumption against them and they are bad and providing actual evidence to support their claims.
philosophically, if it's common for people to experience elaborate afterlife stories when they die, that's prime facie evidence that an afterlife might exist. even if i were to admit that an afterlife isn't most probable... it's objectively possible based on that evidence and all the other lines i've provided. that's why it's objectively irrational to say there's not even evidence for an afterlife.
