Richard Hoover, an astrobiologist working for Nasa has claimed in an article written for the Journal of Cosmology that he has found tiny fossils of alien bugs inside meteorites that crashed into Earth.
Hoover says that filaments and other structures in the meteorites appear to be microscopic fossils of extraterrestrial beings that resemble algae known as cyanobacteria.
Laboratory tests conducted by Hoover on the rocky filaments were not able to find evidence they were linked to Earth-based organisms, because they lacked nitrogen, which is essential for life on Earth.
Hoover is convinced this indicates they are "the remains of extraterrestrial life forms that grew on the parent bodies of the meteorites when liquid water was present, long before the meteorites entered the Earth's atmosphere."
Hoover made the discovery after studying the freshly cleaved surfaces of three ancient meteorites that are thought to be the oldest in our solar system.
Interestingly enough, Hoover has made similar claims before in studies he has made on other meteorites, but nothing has been confirmed yet.
Rudy Schild, a scientist at the Harvard-Smithsonian Centre for Astrophysics and editor of the journal Hoover made his claims in, said: "The implications are that life is everywhere, and that life on Earth may have come from other planets."
Schild has also instigated a process where 100 other scientists would study and comment on Hoover’s findings, thus thoroughly vetting them.
