What makes you think that I subscribe to the belief that we are all individually created by God? The Bible does not teach that.
God created the first pair of everything and left the reproduction up to them.
What you have said is exactly why we should value life...not every egg and sperm gets to make a living human or animal. The odds against us being here as the individuals we are, is infinitely small.....but the odds of you being a human by chance are absolute zero. There is not a single shred of substantive evidence that humans descended from any animal. We humans are unique on this planet....created that way. Science cannot disprove that.
Humans are the product of a gene pool going back many thousands of generations....but animals are so much better at choosing a mate by programmed instinct than we are by choice. Animals choose the best genes to hand on to their offspring....humans choose a mate that appeals to them in ways that don't hand on the best traits....in fact pregnancy often ends up being an unwanted side effect of their all important sex life....providing of course that the sex is between males and females..... which is the actual cause of reproduction.
In today's world the human gene pool is now a cesspool. God help the children of any coming generations if this present crop of youngsters are tomorrow's leaders and voters. The system is broken and human genetics have been contaminated with so many undesirable traits and a predisposition to serious diseases, handed down both genetically and environmentally, that it is impossible to see any improvement in any facet of human endeavor in the future if it was left in their hands.
What future do you see if things don't change?
