Death can not be defeated, in Christianity, it is said that, when the human is resurrected, it will defeat the death itself. The Christians idea of immortality is in resurrection, so it means that the humans can be immortal, sexuality confronts their ideas of immortality. That is why they consider sex a sin. Death is a untested rumor, no one returns to tell their story. The idea of resurrection seems a nonsense, no one would live here again, so they invented that the souls move to heaven and stay in the clouds for eternity. Resurrection and reincarnation are different terms, resurrection is the immortality after death of the same person, reincarnation is the life after death in a new human or other form of life. I do not believe in heaven. Since human minds have more conscious and sense than any other animal, they take death as a dramatic thing. If we were born from nowhere, we could be born again, with other mind, I believe that death is a absolute enigma, from the thing that I was borned on this planet, in the middle of universe, is weird. I do not limit myself to the animals and human forms of reincarnation, I believe that I could be reincarnated as a alien. So, we all were born from nowhere, but death is undefeatable and we will see what can be happened after death. The medieval idea that rock lives, makes me laugh, but their everlasting existence is weird. They also appeared from nowhere, so all these things appeared from nowhere, adding the human world into the eternal nature systems, it makes things more weirder. The everlasting existence of the sun, rock, tree, fog, star, their presence is weird, they appeared from nowhere! Probably made of little weird things. it's weird how human life simplified and mistaken the understanding of nature, some think that the humans are the purpose of world, that death is depressing and it is morbid to some. We all are 99% made of elements, we must accept ourselves as elementals, that are made of nature and belong to it. Decay of corpse and the banishment of life make death appear as everlasting. Nature makes it all for a reason, we leave children as our future and we continue to live in them.
