Such beliefs are based on two "weaknesses" of the human nature:
1) Fear in general and especially fear from death. People can not accept that they are in fact so vulnerable and they can simply disappear. They want to believe that there is something more. And if you want to believe something very much, you believe it.
2) Low IQ. Several 100 years ago the sun would momentarily disappear from the cloudless sky. Most (all) people would say "God", while the correct answer would have been "We don't know why that happened. Maybe in the future science will be able to explain it. Maybe not." Unfortunately most people can not accept that there are many things that the insignificant humans can not know about and therefore they fill in the gabs with "God".
However one of the few things we know is that our existence is very physical and directly related with our brain activity (the neurons that Sotos said). You can even emulate death by being put in a deep narcosis were your brain activity comes to almost a complete stop. When you do that, time "freezes" for you. In other words you do not exist. Death is the complete stop of all brain activity, and unlike narcosis, your brain gets destroyed so you can never "come back".
Still, as the song says: "Don't worry, be happy". So if believing in Gods and spirits makes you feel better, then by all means continue. After all it is much more important to be happy than correct, and if you can not be both then certainly choose the first one.
Piratis,
That was very well explained. Of course, when one is in deep sleep at night time, he might as well be dead, since the person has no idea what is happening around them, even though, the brain is active "directing traffic" within the body.
