I think the easiest thing to believe is that we are extremely evolved in respect to the most predominant fear of every person - death. There must be an auto-pilot that takes over and makes us feel at peace as we die. However, that doesn't explain all the information that NDE experiencers return with - like accurately describing conversations that happened outside the operating room while surgery was going on, or seeing and accurately describing the details of a long-since-deceased family member. It's definitely one of the biggest mysteries and it's likely to go unanswered (at least in my lifetime). Either way it goes, at least in death we will know (even if only for a brief moment or eternity) something that we most likely never knew in life. I suppose it's personal preference. If, through your own experiences, your inclined to believe or not, then it shouldn't be a struggle and your belief shouldn't trouble you. I'm keeping an open mind and will continue to try and learn more where I can. Like spotflare said, there's only 1 way to really know.
@Dejin That actually isn't true. The majority of the world did not think of the world was flat, mainly only the UK did. And before their time, there is evidence of no such belief in earths "flatness" @Snuffy TheKiller. No, I have not died and or came back. Many who did seem to think they saw something when they did, however. Does that mean they are wrong? Does that mean you are right? No. There is a thing we know of as faith. For those of us who have experienced something beyond the normal, it reinforces said faith. It becomes factual to us. Faith becomes belief. To those who refuse to see or witness and explain away, nothing ever changes. I'm not saying who is right or who is wrong. I'm simply stating, that many people have experienced something outside the normal, things that science cannot explain. Believe it or not, but do not force you belief in the lack of something onto others, the same as you do not wish those who believe to force that belief on you.
I watched S1... then S3 and the first few episodes of S4. I missed S2, but am watching it now. I can not believe how big of a douche Theon Greyjoy was in S2! I was kinda feeling sorry for him losing his wanker and being turned into a medieval princely-gimp... now it seems he deserves it, but, then again, he did have a confusing childhood. That was funny, when he got the horseback ride to the castle from his sister, he was feeling like a rock star...
