1. We don't know how to create human life from non-life yet
Although we have certainly created a synthetic bacterial cell, we have not created a synthetic human cell. The biggest difficulty would probably be the multicellularity. How does nature coordinate all the cells together to function as one organism? There is so much in nature that has not been revealed yet. We are not even close in engineering human life from non-life.
The only way we can "create" new human life is to do what our ancestors have always done: fucking. Maybe someday, we will be able to invent immortal robots, so that even though our flesh-and-blood bodies die, our immortal robots have our memories and identities stored in huge databases. Humans will never have to fuck themselves anymore to replace old individuals. Instead, immortal robots will slowly replace every human life, until the world is overtaken by these sexless, immortal robots. They are sexless, because they don't need to exchange genes or reproduce. They are immortal and can self-heal. They derive their energy from the sun and from solar power plants that fuel the miniature humanoid robots; in other words, they are a better form of us, because they can photosynthesize. In addition, we humans sometimes make irrational, impulsive decisions; robots, on the other hand, will take human rationality to the extreme.
Humans will never have to fuck themselves anymore to replace old individuals.
2. We don't know how to bring people back to life
Once people die and start decomposing, they stay dead. It is not possible to bring people back to life or to reverse decomposition. Decomposition is an irreversible process, because the tiny microorganisms are eating you from the inside out, and your own body cells are dying. The good thing about decomposition is that, if humans let themselves to be thrown on the soil instead of buried in caskets or cremated, then the decomposed human body will be recycled.
3. Youth is short
Humans are unique, because they have a long childhood or delayed adolescence. Approximately 10 years are devoted to developmental growth, but that may be changing, as children are now entering puberty at earlier and earlier ages and becoming more knowledgeable about sex through age-inappropriate media.
About 20-30 years are devoted to growth and development. Given the long lifespans, the initial 20-30 years are only a small fraction of the lifespan.
4. Reproduction is limited to your teens and young adulthood
Humans are extremely fertile in their teens and twenties and maybe even thirties. But then, the ability to reproduce declines, as females go into menopause, and you can't reproduce when your other half becomes infertile. So, if you want babies, then you have to decide that for yourself as early as possible. If you decide too late, then you can just adopt the babies from other couples.
Therefore, young people should be grateful that they are pregnant, even if the pregnancy is not wanted. A pregnancy is a blessing, because without advanced medical technology or health insurance, it is kind of difficult to get a pregnancy. In that light, abortion is evil, because the person who has been blessed with a child takes away the child's life before it has a chance to live outside the womb and robs older, childless straight couples and gay couples from the opportunity to adopt. If the baby does not have a serious birth defect and poses no serious threat to the mother's health, then the baby should be born. Being a rape victim does not excuse a person from abortion, because the baby may be born perfectly healthy and live in an adopted home.
