I can't grok why do people have so much issue with accepting the simplest explanation - physical laws still apply and our minds exist within them, as part of that grey goo inside of our skulls. Isn't it already amazing enough that something like that is possible? I mean we don't believe in fairies and santa claus anymore since we know how and why they were made up, but sure there is some utterly inexplainable magic that breaks all physical laws that we know... just to feel more special? Give our immortality a chance? I do believe a lot of weird, illogical and sometimes completely fucked up beliefs simply come from common utter dismay of most folks when confronted with their mortality and the very real and perfectly fine chance that once we die that's it, our version of this universe and all of our experiences, loves and fears will simply vanish, forever. Every single religion primarily address this fear, the rest are mostly rituals folks made up early enough for them to stick around and management political structures just like in any other office. For people brought up in religion this is simply unacceptable, whole world falling apart. Why any parent still does this to their children is completely beyond me, but I guess road to hell is often paved with good intentions. I may be wrong and most logical solution may not be the right one, and that would make me in fact very happy. But religious people are mentally cornered, they can't accept any other option without their world breaking apart in the seams. That's a position of weakness and fear on the most important topic in life.
