Top secret document called Relations with the inhabitants of celestial bodies, written in 1947 by the atomic physicist J. Robert Oppenheimer and the famous physicist Albert Einstein, officially mentions for the first time extraterrestrial biological entities (EBE). The document states, among other things, that the presence of extraterrestrial spacecraft is understood as a military matter and that we have been confronted with this fact since June 1947. (The Roswell incident did not occur until July 2, 1947.)

The document discusses the topics that the scientific community should address: where they come from, what impact it will have on our legislation, what we should do in the case of colonization or integration of EBE among humanity, and also why they are here. The document states that if the aliens decide to stay on our planet, it is necessary to reckon with major changes in the common understanding of the laws. You will need to create a new law that will regulate the interaction between planetary views.

The document also mentions the presence of alien ships in connection with our modern first nuclear weapons attempts.

Veterans Today (an Internet portal for former US State Department employees and intelligence agencies) says world governments are in contact with extraterrestrial civilizations.
