Aliens are often depicted as little green men with large black eyes. While this is a generic description, there are a few things about aliens that are sometimes hidden from the general public. There are over 17,000 stars that could possibly have the same structure as Earth and could support life of some kind. Mars is one of the top locations where alien life could exist because of the atmosphere. In 1450 B.C., Egyptians saw bright lights in the sky that resembled UFOs. In 1957, a farmer in Brazil was working on his farm when he saw what appeared to be an alien walking toward him. He was then covered in gel before the alien left. The universe is an abundant size, and there are numerous stars in the universe. Scientists have explored the concept that if there are that many stars and planets, then why does only one planet have life? As scientists explore Mars and other planets, they continue to find evidence that there is water on Mars and one of the moons of Jupiter. This is an essential component to support any kind of life, whether it’s plants or people. The Earth is a little over 4 billion years old. Life started about 3.4 billion years ago. This doesn’t seem probable to some scientists who believe that bacteria and smaller lifeforms developed from something else that landed on the planet beforehand.
