Venus -
What Shepherdess said is correct. What you said is not.
1 - People did have many children centuries ago but then many children died in childhood.
2 - Kings did have many wives in some societies. Do you really think that this example you give demonstrates the norm amongst the population as a whole? If so how did the man support all these wives and children?
3 - Your post is a good example of the 'non sequitur' argumentation mistakes often used by creationists. Your conclusion does not follow from the evidence you provide. I am going to assume that you simply do not know why what you have written does not support your assertion...
