There is an idea that is utilysed frequently in science fiction that we might someday evolve into beings of pure energy and shed our mortal bodies. It's utterly preposterous, yet many support it as zealously as any religious fanatic.
Many people have this wishful thinking syndrome. They wish that everything that they had ever been taught, all the traditions, weren't completely invalidated by critical reasoning and rational thought. Thus, they create a way for there to be a spirit or spiritual energy that becomes through the process of evolution.
This line of thinking is anything but rational or reasonable. There are not now nor will there ever be such a thing as energy beings.
