The Human Brain and Body may be an organic machine, but little is known about what exactly the Mind is and hardly anything is known about Consciousness( your direct state of awareness) or what exactly it is, humans do however know of a few practices and techniques that can be used to show some of the potential of the mind, these practices are Lucid Dreaming and Astral Projection and they show that Consciousness is very 'flexible' and could in fact exist without the body, near death experiences and experiences with substances such as DMT also suggest this...so suggesting things such as when life on this planet 'dies' theres nothing is just as ignorant and extreme as thinking life will suffer for all eternity if they do not follow the certain rules of a specific documentation... the fact is no one really knows, we only know what we can observe and analyze what nature has provided us with and considering we know absolutely nothing about the grand scheme of what this universe or universes hold it would be very primitive and moronic to come to a conclusion about what happens after we 'die' on this planet, maybe we should strive to be more curious on this matter and start considering what exactly Consciousness is.
