A reply from earth? - A proposed approach to developing a message from humankind to extraterrestrial intelligence after we detect them

The question of the formulation of a proper response to the detection of an extraterrestrial civilization is considered. It is proposed that an international agreement or declaration of principles establishing procedures enabling international participation in the making of such decisions be developed and that the SETI Committee of the International Academy of Aeronautics, in cooperation with other interested bodies, draft an agreement or declaration of principles that would set up these procedures; and that the draft be presented to the United Nations for consideration through the Committee on Peaceful Uses of Outer Space. A suggested outline of the agreement or declaration is presented and proposes that a response to the detection of extraterrestrial intelligence should be on behalf of all humankind; that this decision should be made by an appropriately representative international body; and that the content of the reply should reflect an international consensus.
