What should the world be like?

Imagine you had complete political control over a brand new planet with 6 billion people living all around it, reproductive abilities similar to ours, internet, satellites, combustion engines, and all the other technologies we’re used to in our world. Almost everything about them is the same as us really except one thing: They just popped into existence and they need some direction, a hint at how to begin living together on their almost identically similar Earth-like planet.

They’re going to need access to resources for everyone and a way of living life that their planet can withstand.

What do you advise that they do?
Would you suggest dividing into separate countries like we have?
Would you suggest creating a stock market?
Would you suggest monogamous relationships?
Would you suggest farming and domestication of animals?

Get creative and critical. What do you suggest these 6 billion people do for the long-lasting good of their existence.
