Social Evolution: Where to Now?

Or born in Ancient Egypt and believed your Pharaoh was a divine God, where people had different beliefs and viewed the world quite differently than we do today? So how did the human race arrive at where it is today and where it is heading in the future? What do we need to do in view of overpopulation and climate change ?
