We discuss how to be a good and friendly alien by trying to analyze an alien civilization's rules of ethics and incorporating them in our policy. We bring up how regardless of their level of civilization, we must first change our way of treating animals on this planet before expanding our principles into the intergalactic space. We emphasize the importance of making partners in the Universe considering humanity's fate that has been lonely since its beginning and how important it is to understand and respect their rights to make ourselves companionable. We also discuss how we can present ourselves as non-threatening and friendly and whether we must even present ourselves that way in the first place.
