The Bible that was abridged by King James is relatively new in the scheme of human time, yes, but the commandments that were given to Moses was the first law (and is in the Bible), and is influential to mostly all human laws.
Moses was not the first to deem that killing is "wrong." Long before Moses, killing for example was counter productive to most species of animals, until we become over populated. Stealing wasn't illegal, but if you did it, you would be attacked by the person you stole from. What this means is, Moses may have written them on paper, but the bible is not the basis for human law, it's productivity.
Goodness, this is such an ignorant statement. Most of our Earth is uninhabited. There is plenty of room for even more people. Just because we crowd cities so bad and end up in high rises, doesn't mean we are overpopulated.
Correction, most of the earth is uninhabitable. Many places are not living conditions deemed suitable for human life yet, people live there. Why? Because they can't go anywhere else. Don't tell me it's ignorant, when people don't get food, because they grow any where they live, or they can't afford it. It means there's too many of us and we need a pandemic, since we are long overdue.
There are currently about 6 Billion people on this planet. Lets put them, four to house on a quarter acre of land. This is the typical size of a traditional suburban lot. Now, physically how big is the suburb of houses we’ve built?
So, 6,000,000,000 people; four to a house is 1.5 Billion houses.
1.5 Billion Houses on a quarter acre each is 375 Million Acres.
How big is 375 Million Acres? The state of Texas is 171904640 acres.
375 Million Acres is just over twice the size of the State of Texas
It also equates to 3.6 Californias. Alaska at 420 Million Acres could hold them all and still have 45 million acres left over.
Now this, is what I call ignorant. If you want to live in a world of just houses, fine be me, pack all the people in the world into Alaska. Where are they going to farm, hunt, get medical treatment and what infrastructure will they use to get there? You need to rethink your calculations and the amount of habitable land we actually have.
