Extraterrestrial life is hypothetical life that may occur outside Earth and which did not originate on Earth. Such life might range from simple prokaryotes (or comparable life forms) to intelligent beings and even sapient beings, possibly bringing forth civilizations that might be far more advanced than humanity. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as astrobiology.
Since the mid-20th century, active ongoing research has taken place to look for signs of extraterrestrial life. This encompasses a search for current and historic extraterrestrial life, and a narrower search for extraterrestrial intelligent life. Depending on the category of search, methods range from the analysis of telescope and specimen data[4] to radios used to detect and send communication signals.
The concept of extraterrestrial life, and particularly extraterrestrial intelligence, has had a major cultural impact, chiefly in works of science fiction. Over the years, science fiction communicated scientific ideas, imagined a wide range of possibilities, and influenced public interest in and perspectives of extraterrestrial life. One shared space is the debate over the wisdom of attempting communication with extraterrestrial intelligence. Some encourage aggressive methods to try for contact with intelligent extraterrestrial life. Others—citing the tendency of technologically advanced human societies to enslave or wipe out less advanced societies—argue that it may be dangerous to actively call attention to Earth.
Aliens in India?
A much-anticipated report by the United States government, published last month, may have left conspiracy theorists and self-proclaimed extraterrestrial investigators disappointed in their expectations, but it probably has not dimmed their enthusiasm one bit in spilling the beans. The report, reviewing as many as 120 incidents of unidentified aerial phenomena ("UAP"; somewhat of a deviation from the more popular term - "UFO") in the past two decades, said that there was no 'conclusive evidence' linking these sightings to any actual extraterrestrial contact. However, the Pentagon was careful enough not to rule out the possibility of such.
Alien life enthusiasts, many of them right up the alley with QAnon acolytes and flat-earthers, observe World UFO Day on July 2 with a host of their favourite conspiracy theories on the web. Much remains to be said, though, about "UFO sightings" and the related science-fantasy fanaticism in India.
Hollywood may have all but ensured that whenever extraterrestrial life does contact our species, they would choose the United States as their preferred destination. Despite such odds against popular imagination, talks of sighting unidentified flying objects here in India have been up for decades.
