The question "Is there life on other planets?" it started from the beginning of the human obsession with space and is still waiting for an answer. The Catholic Church violently punished early astronomers who searched for life on other planets. For years people saw these astronomers as heretics because they went against the church and were undesirable, but today there may be evidence to support these astronomers. Today we find that individuals are still divided or not divided between believing in alien existence. People devoted to religion tend to disagree with the option of living somewhere other than Earth as it goes against their beliefs. However, with the rise of realistic alien films and plausible theories, many young people are starting to think that life on other planets doesn't seem so radical after all. Scientists are finding more and more predictive evidence every day that leads most of them to think that other planets have life. Say no to plagiarism.

These theorists studied the history of early civilizations and claimed to have found historical and religious texts full of ancient alien connections. Theorists are said to be able to decode ancient paintings of aliens and their spaceships. According to History Channel's Ancient Aliens "Swiss author Erik Von Daniken put forward the hypothesis that, thousands of years ago, space travelers from other planets visited Earth, where they taught humans about technology and ancient religions." The pyramids of Egypt were so complex to build at the time with limited technology, that these theorists believe ancient aliens came down and helped the Egyptians build them. Theorists also believe that aliens went to places like Easter Island and built the statues, as did other early civilizations in South America. The early appearance of life on Earth suggests that there is a good chance of spontaneous generation of life under suitable conditions. As for scientific research, scientists have been able to find some evidence that could lead to the discovery of life in the future. First, let's start with the elements necessary for life. Scientists were able to discover that oxygen and carbon exist on other planets. Scientists have found a planet they believe is similar to Earth but larger and with extreme weather. “Researchers from the University of Chicago and Northwestern University assume that there are about sixty million potentially habitable planets in the Milky Way” (Arnold). Water is a fundamental component for the sustainability of life. According to NBC News, in our solar system alone, scientists have detected water on Mars and Jupiter's moon Europa. Not to mention that life tends to survive in the worst conditions, as it survives in the depths of the dark ocean. There is a possibility that life could exist in the water of these planets and moons in our galaxy. According to Roudman, scientists specifically look for habitable planets around red dwarf stars. They believe the first planet on which life is found would be around a red dwarf star. According to many scientists, about fifty percent of red dwarf stars should have a planet in the habitable zone. Red dwarf stars are definitely targets if you are interested in finding planets that support life. However, red dwarf stars share the danger from radiation. Additionally, NBC News confirms that NASA has detected radio signals picked up by the radio telescope.However, scientists attribute the signals to human interference from satellites. However, NASA plans to launch the Transiting Exoplanet Survey Satellite to search for planets. We are still at a starting point for the exploration of life on the planet. Earth, our planet, is one of billions of planets in our ever-growing universe. The possibility of life on other planets is very likely. However, the possibility of them visiting us, or us traveling to them, is very unlikely. As for other life forms, it would be difficult for them to get past satellites and space junk to visit Earth. Even if people claim to have sighted UFOs, this is their word against others and cannot be clearly identified to be considered concrete evidence. As far as we are concerned, the law of physics is universal, which means that travel is almost impossible. The speed of light travels at speeds impossible for humans and it would take light years just to reach another solar system. There is also the possibility that aliens cannot or do not visit us, just as we cannot visit them. If life exists on other planets, we have no way of visiting them at the moment. Although the idea of ​​little green men in spaceships has been generally rejected. People are still led to believe that life exists on other planets. Even if there is no evidence proving the existence of aliens, realistic and convincing films tend to influence people towards the belief in alien existence. Popular culture has created a fad about aliens and increased humans' curiosity to discover the truth about other life forms in the universe. Another factor that has only increased curiosity is Area 51. Area 51 is a United States military base where many alien life advocates theorize that the government is withholding information about extraterrestrials. Even though Area 51 is just a conspiracy theory, the idea behind it has made the possibility of aliens even more interesting and made people even more curious. The probability that there is life on other planets has yet to be calculated. There is always the possibility that Earth really is the only one to host life and all these theories would go to waste. Some people suggest that life came to Earth from elsewhere. They believe that life existed before Earth and continued to grow on other planets after Earth. These same people believe that there are seeds of life in the universe. With the abundance of planets and galaxies in the universe, it is also likely that we have overlooked planets with life. We could also have assumed that some planets are incapable of supporting life and ignored them when in fact they might have life on them. There is also the possibility that life on other planets could be strange or threatening to humans. In that case, finding extraterrestrials would prove destructive.

Although scientists have found a lot of predictive evidence, it is not enough to put the pieces together and correctly state that life exists on other planets. However, there is no evidence that clearly demonstrates that life on other planets is impossible. The struggle for scientists is the lack of technology to travel to other galaxies or clearly see the transmission from our galaxy to other galaxies. Even if life existed, there is a possibility that aliens do not want to be found or that we may have overlooked them. However, space exploration is..
