Right after celebrating Neil Armstrong and Buzz Aldrin’s first steps on the moon back in 1969, on 20 July, scientists suggest that the first beings on the moon were not the humans that visited it.

Our closest neighbor might have had some extraterrestrial life after it got blasted by a meteorite. And once it impacted the moon, it could have created an atmosphere a lot more habitable than today.
Dirk Schulze-Makuch, an astrobiologist at Washington State University and with Ian Crawford, a professor of planetary science and astrobiology at the University of London are the authors of the study which claims that the Moon could support simple life form 4 billion years ago. The peak conditions to harbor life were among the time when there was also volcanic activity 3.5 billion years ago.
That made the moon spew out a lot of hot gas, along with water vapor. The gases could have formed into liquid water on the lunar surface, explained Schulze-Makuch:
“If liquid water and a significant atmosphere were present on the early Moon for long periods of time, we think the lunar surface would have been at least transiently habitable.”
An atmosphere and a magnetic field would have made the Moon the perfect place for life forms living safely from solar winds.
Microbes Living on the Moon
According to researchers, the earliest evidence of life on Earth dates back to 3.5 – 3.8 billion years old. They were the cyanobacteria which may have remained on the Moon after a few meteorite impacts. Theia, an early planet, and Earth crashed, creating the Moon about 4.5 billion years ago. As the moon formed, it might have retained some water.
Then, as meteorites smashed off the Earth’s surface, landing on the Moon, probably carrying the cyanobacteria which could have survived the impact.
“It looks very much like the Moon was habitable at this time. There could have actually been microbes thriving in water pools on the Moon until the surface became dry and dead,” explained Mr. Schulze-Makuch.
Both authors hope that NASA or other space agencies will continue lunar exploration and examine moon deposits to see if they once included signs of life. An alternative would be to simulate the conditions on early Moon or Earth on the ISS to see if the theory can be proven.
