Ancient Aliens – The Space Travelers: It is humankind’s most profound achievement: blasting off into the stars. But is it possible that our voyages into the cosmos are really a return to our true origins? And if so, as we venture out further into outer space, will we encounter space travelers from other worlds?
Ancient Aliens is an American television series that premiered on April 20, 2010, on the History channel. Produced by Prometheus Entertainment in a documentary style, the program presents hypotheses of ancient astronauts and proposes that historical texts, archaeology, and legends contain evidence of past human-extraterrestrial contact. The show has been widely criticized by historians, cosmologists, archaeologists and other scientific circles for presenting and promoting pseudoscience, pseudohistory and pseudoarcheology.

Human spaceflight (also referred to as manned spaceflight or crewed spaceflight) is spaceflight with a crew or passengers aboard a spacecraft, the spacecraft being operated directly by the onboard human crew. Spacecraft can also be remotely operated from ground stations on Earth, or autonomously, without any direct human involvement. Persons trained for spaceflight are called astronauts, cosmonauts, or taikonauts; and non-professionals are referred to as spaceflight participants.
The first human in space was Yuri Gagarin, who flew the Vostok 1 spacecraft, which was launched by the Soviet Union on 12 April 1961 as part of the Vostok program. Humans traveled to the Moon nine times between 1968 and 1972 as part of the United States Apollo program, and have had a continuous presence in space for 20 years and 117 days on the International Space Station (ISS).
To date, Russia, the United States, and China are the only countries with public or commercial human spaceflight-capable programs. Non-governmental spaceflight companies have been working to develop human space programs of their own, e.g. for space tourism or commercial in-space research. The first private human spaceflight launch was a suborbital flight on SpaceShipOne on June 21, 2004. The first commercial orbital crew launch was by SpaceX in May 2020, transporting, under government contract, astronauts to the ISS.
