Since ancient times, we have always harbored a curiosity about the exploration of extraterrestrial life, and as a result, we have flown countless imaginary characters into many extraterrestrial creatures, ranging from deep audiences to terrifying shapes. However, deep down we are deeply aware that those images of extraterrestrial creatures, whether spectacular or terrifying, are nothing more than the creation of human beings based on longing and imagination. So, what will the extraterrestrial life that has ever visited Earth look like?
As we all know, the key factor behind the rich and colorful treasure trove of life on the earth is the widespread distribution of liquid water resources, so we often use the term "water - the source of life" to describe this amazing phenomenon. It is widely believed that the universe contains so little water that it is difficult to find a planet with a vast ocean like Earth.
However, the vast expanse of ocean water around the world, and enough carbon to shape life, can be found virtually everywhere in the universe. Water molecules are mainly composed of hydrogen atoms and oxygen atoms; Hydrogen atoms exist in the universe in extremely high abundance, and their proportions exceed even the sum of all other elements in the universe. Comparatively speaking, oxygen is the third element, followed by carbon in the fourth place.
Therefore, from this perspective, there is no shortage of water and carbon resources necessary for the formation of life in the universe. However, these basic elements alone are not enough for living beings to be born and thrive. Stricter constraints, such as a thick atmosphere, a stable magnetic field, and a suitable temperature in the habitable zone of stars, are necessary to maintain the liquid stability of water on Earth, thus providing the necessary support for biological evolution.
In fact, many planets are not in habitable areas and do not have the same surface temperatures as Earth's, but because of the extreme cold on their surfaces, the water at low temperatures can freeze and envelop the entire planet, hiding large amounts of liquid water beneath the solid ice. One of the most famous examples of this is the Europa moon in our solar system.
Europa's surface is covered with ice, and the tidal action of Jupiter, the ruler of the solar system, continues to erode and compress, making the oceans inside Europa active. In such a warm environment, the likelihood of life in the underground ocean of Europa is theoretically greatly increased. Because in this way, after the stars that exist in the universe, the form of life forms may be very different from ours.
We can even imagine that perhaps most of the extraterrestrial life in the ecosphere of carbon-based organisms is manifested through water-based survival. Under this premise, is it possible for those ancient legends that have been sealed for a long time to become a reality? For example, Atlantis, a prehistoric civilization that was revered as a prehistoric civilization that disappeared into the depths of the ocean, is recorded to have sunk into the sea to produce Naga, the mother of mermaids and octopuses with human appearance but upper body with a hand-like structure.
If Atlantis is regarded as an underwater civilization from the extraterrestrial world, then the legendary mermaid and Naga may really be intelligent creatures from the outside world. This fantasy is not groundless, the depths of the ocean are indeed full of unknowns, and we have wondered if the octopus located in the brain of Jiumen is really the offspring of extraterrestrial life. It now appears that the octopus may not be an alien entity, but it is more likely that it was just a pioneer of biological experiments that was intentionally released on Earth about 500 million years ago on a mission to sift through organic matter. And their true form may be like the beautiful mermaid or the eerie Naga.
In summary, considering such a unique and hidden life form, these witnesses may not be able to see it, and the reason for her true purpose is that they have shown a strong interest in the ocean floor of the Earth, and although we have not yet received any obvious signals from extraterrestrial life to officially visit Earth and communicate with us, we are still full of anticipation and confidence in the future!
