If an alien ship were to land in your backyard and choose you as the earthly representative of humanity, what would you tell them about our world? Would you consider going back with them for a visit?
Paraphrasing Kurt Vonnegut, I would say that we are a violent people who believe we are gentle; we are a hate filled species who think we are lovers. Please do not judge us by what you see. Learn our history, our whole history, especially what we call our "prehistory."
Read our hearts, if that is within your capacity. Then you may tell us what you know that might help us. If you think the teachings of Lao Tse, Buddha, and Jesus are useful, remind us of that. Give us hope that these principles are universal and not just of the earth
