I would make Humans with a balanced Right and Left Brain. Would center each person with Love, so that Love would motivate all their words and actions. Love for the Animals, Earth,Plants, Trees. Love for all their Brothers and Sisters I would put on the Planet. Their Love Center would hold The Earth Scared, and make decisions based on how their actions would benefit the Earth, and all their Brothers and sisters.
Their Love Center would motivate them to use only what they need. Selfishness would be abhorred and distasteful to them.
I would teach them that this Paradise I gave them would always remain a Paradise if they would always be Centered in Love for all their thoughts, deeds, and actions.
