Is Earth the only planet in the universe that harbors life? Are humans alone in this vast cosmos? Since humanity realized that Earth is not the center of the universe, speculations and imaginations about extraterrestrial civilizations have never ceased. With the advancements in astronomy, biology, radio technology, and space exploration, the existence of extraterrestrial life is no longer a myth but has become a serious scientific inquiry.
The Moon, as a celestial body near Earth, has always been a significant target for the exploration of extraterrestrial life. Early on, some believed that aliens might inhabit the Moon's interior, even proposing the hypothesis that the Moon is a hollow body. However, scientific research has proven that the Moon is not hollow and does not possess conditions suitable for life. These speculations were ultimately debunked by reality, becoming subjective conjectures made by humans based on scientific observations.
In the 1930s, an article in the New York Sun caused a huge sensation, claiming that astronomer William Herschel had discovered signs of life on the Moon. In reality, this was a fabrication by British writer Richard Adams Locke known as the "Great Moon Hoax." Science has shown that the telescope technology of that time could not distinguish objects as small as 45 centimeters on the Moon's surface, and the Moon's lack of water and atmosphere renders it a desolate world.
With technological advancements, humanity's exploration of extraterrestrial life has become more scientific. Scientists speculate that other planets in the universe may also harbor life by studying the evolutionary processes of life on Earth. However, even if the conditions for life as we know it exist, the forms of life could still be diverse, such as silicon-based life or energy-based life. Currently, no evidence of life has been found on other planets within the solar system.
Nevertheless, human research into extraterrestrial life continues, and there may be new discoveries in the future.
