The challenges to confirm the existence of extraterrestrial life on Earth

Despite evidence pointing to full disclosure that extraterrestrial life is present on Earth, “questionable data quality and a lack of shared research standards” continue to plague the scientific community as it consolidates research. about the UFO phenomenon, argued author Leonard David in American Scientist. Against the backdrop of a year of massive efforts by the (US) Congress and new funding for the Pentagon to investigate UFOs, the article outlines ways to overcome the challenge s. The first big challenge is the lack of conclusive photographic evidence of aliens and their machines. Harvard University astrophysicist Avi Loeb told David for the article: “A million blurry images are worthless compared to a single high-resolution video resolving an object as it maneuvers.” A custom observatory, costing around $300,000, is expected to overcome this major problem. The observatory is cap...

Seti: why extraterrestrial intelligence is more likely to be artificial than biological

Is there intelligent life in other parts of the universe? It is a question that has been debated for centuries, if not millennia. But only recently have we had a real chance to find out, with initiatives like Seti (Search for Extraterrestrial Intelligence) which uses radio telescopes to actively listen for radio messages from extraterrestrial civilizations. What should we expect to detect if these searches are successful? My suspicion is that they are highly unlikely to be little green men, something I speculated about in a talk at a Breakthrough Listen (a Seti project) conference. Suppose there are other planets where life began and that it followed something like Darwinian evolution (which need not be the case). Even then, it is highly unlikely that the progression of intelligence and technology will occur at exactly the same rate as on Earth. If it was significantly delayed, then that planet would clearly not reveal evidence of extraterrestrial life ...
