Many believers have turned the tables on the idea of fear, and made it into the excitement of an afterlife. They have unknowingly suppressed the very real fact that once our bodies die, there is literally nothing for them. From what we are now able to measure and observe, and what we have collectively experienced since we created communication as a species, there is absolutely nothing at all to indicate that there may be something after death. It is so far beyond possible, as to render it nothing more than a human fantasy, and one that is wholly driven by the fear of nothingness - death.
Humans have been "philosophizing" forever on this topic. We think we are smart, and in so many ways, we have become very knowledgable. But obviously, we still have a lot to learn. And this is why I love the scientific approach. So, we start with crazy notions, thoughts, ideas, and philosophies on the things we do not fully understand, which triggers a more rigorous investigation, which becomes information that we can use to make things "better". Better is subjective, I suppose.
One additional thought on the religious side of humanity. Many believers want to know why we are here, or what is our purpose. They literally do not grasp the possibility that we are here as the result of an undirected cosmic accident. If we evolved from simple life, which was triggered by a random combination of chemicals, and there is truly no "direction" in the apparent resulting tree of life, then there is no "reason" we are here. We are just here. Some of these same believers would tell you that every living thing has an actual purpose, as a part of the plan of some creator? Yet, death seems to be as much a part of life as birth. It would seem that the creator intended death to happen, and planned it that way all along. But believers cannot accept this, so they invented the afterlife, and are convinced that this was the intention all along.
How sad is it that humanity has gotten itself caught up in the afterlife debate, and attached it to a creator that is not measurable in any way. A purely imaginary entity that MUST have created this circus we appear to live in, and then through the magic of ancient writings, from oral traditions, is still trying to tell us that we must all worship him and accept his son's death before we will be granted eternal life.
Jesus Christ on a stick. God is death, that's the whole problem.
