Why do people want superior offsprings?
Your job is to find a mate that matches up to your level or even surpasses your level so you can mate and produce superior offsprings. Why?
Because there is such thing as reincarnation, based on lots of known facts and testimonials. After you die, your soul needs to reincarnate. Your soul needs to find a new body that closely resymbols your previous body. If you are a black person, you cannot reincarnate into a white person because the DNA doesn't match. You probably cannot even reincarnate into your neighbor's baby's body just because both you and your neighbor are black. The new body your soul shall reincarnate to must closely resymbol your previous body. The DNA must match or be extremely similar.
So your job is to find a mate that's superior. Superior mate can help you produce superior babies. You can then later reincarnate into your great grand child's child, or something. The more superior your offsprings are, the better is your chance of survival. I mean you don't want to reincarnate into some ugly dude's body, do you? You don't want to reincarnate into somebody who carries a disease or is handicapped, do you? So of course men like pretty girls and girls like handsome men. You guys should thank Sierra. If she didn't come here, I won't be here that much.
Since I am immortal I will not be producing offspring by choice.
Reincarnation took place for a long time, but now has ended. Reincarnation is now over. This is the life of all your lives given the age we are in. Time itself will no longer exist as we used to perceive it in the next decade. You may have noticed that there seems to be so little time these days and that the years go by faster. It is because time as we used to perceive it is running out and will end soon.
It is an immortal's nature to perfect themselves, and the higher evolved beings I have seen usually have few children. Usually a smart couple will have one child and put energy into them and their education.
Reincarnation is a process the soul experiences until it becomes physically immortal. This realm isn't able to support immortals though, so earth is going to have to change to support countless numbers of non-decaying super humans. There is already a place like this. It's called heaven, a physical place, more real than what we experience as real here.
Heaven is boundless, and it is also a state of being. It is inside us, and it is around us. We carry it with us, and we create it. It is a timeless realm, and those who have it are ageless.
