The question is on everyone's mind. People around the world dedicate their lives to finding the answer. Does alien life exist? There is evidence for habitable areas in the solar system and ways to learn more about them, for planets that meet some of the qualifications, and for a wide range of reactions in finding the answer. Nowadays, there is about as much evidence that aliens may exist as there is that they don't. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essay Numerous exoplanets, planets that lie outside our solar system, have been found using Kepler space telescopes. So far, 47 of these have been found to meet Earth's habitability criteria. By scientists studying the light cast on exoplanets, specific color wavelengths will appear when certain elements are present. The appearance of oxygen or other elements necessary for survival could mean that life is present. However, there may be a possibility that aliens have adapted for survival through the use of different chemicals, which scientists may pick up, but not know they have found an answer. Life on Earth can exist in extreme environments, and this may also be the case for extraterrestrial organisms. Some types of archaea and other organisms can thrive in extreme conditions. The Curiosity rover concluded that ancient Mars was warmer and had the right chemicals and energy sources that helped life thrive. Jupiter's moon Europa has a 3,100 kilometer frozen ocean. The idea of ​​chemical reactions occurring when water interacts with the rock surface producing nitrogen, carbon, phosphorus and other gases could mean that life could survive in that environment. Previous discoveries have shown that radiation on Europa destroys the possibility of any life, but new research has shown that just one centimeter of ice in low-radiation areas contains amino acids, vital for survival. Life also needs energy, which Europa's tidal bending can provide heat for chemical reactions that can provide energy. As for how humans would respond to the discovery of alien life, it depends on the circumstances. A study conducted at the American Association for the Advanced Science concluded that most people would respond with positivity rather than indignation or fear. The difference in circumstances between discovering alien life and encountering alien life is very different. Vakoch, a psychologist who works on creating interstellar messages, has found that those who are secure in their beliefs are more likely to welcome extraterrestrial life.

There are habitable exoplanets and ways to learn more about them, planets that appear unable to support life that meet some of the qualifications, and a wide range of reactions to the answer. These facts are enough to convince people of the existence of aliens, or the face-to-face meeting will only convince one person?
