It has been centuries now since humankind looked up to the sky and wondered, is there any other life out there apart from our own? Ever since that question has been asked, it's been a mystery. Humans have created fiction of other life forms to fill out our curiosity of the unknown to us.
Many scientists and astronomers are trying to find evidence of other living creatures and things out there in the universe. For example, NASA has discovered that there might be life on the fourth planet from the sun, Mars. According to NASA administrator Daniel S. Goldin issued a statement saying, "NASA has made a startling discovery." Many NASA's scientists do back up their statements with evidence although other scientists do not agree with NASA's announcement about life on Mars. Ever since NASA has discovered living things on Mars, Mars has been the center of attention in the world of science.
Even before the discovery of extremely small, single-cell creatures that somewhat resemble bacteria on Earth, a group of scientists found a meteorite approximately "the size of a large Idaho's potato" on the Antarctica ice field. The meteorite originated from Mars before it came to the Earth's surface thousands of years ago. This was determined when scientists compared the composite of the meteorite with what Viking 1 and Viking 2 had collected. These probes were the first two probes that landed on Mars and analyzed the sample of the Mars soil and atmosphere. After this discovery was made, NASA scientists started to make several tests using a lot of sophisticated equipment. NASA scientists were very excited when they heard this meteorite came from Mars. What makes this finding even more interesting is that scientists found out that these remains consists of a group if carbonate globules. These carbonate globules are "a mineral that crystallizes in the presence of watera key ingredient for life" (Naeye 49).
Bacteria on Earth also produce the same carbonate substances and that is why they were excited about it. Accompanying the carbonate was the substance called polycyclic aromatic hydrocarbons (PAHs), which bacteria and other living things commonly produced. These substances (PAHs) are made up of hydrogen and carbon. Nevertheless, not all scientists agreed with this finding, because they said that the PAHs substance could occur in almost anywhere without having anything to do with life. For example, it could occur in a car exhaust or in a chicken on the grill (Shreeve 40).
A group of scientists from New Mexico also conducted an experiment of their own on the same meteorite that NASA used but their results were different of those from NASA. They found no evidence or trace of life form in the particular rock (Fleck). They said that they did not find anything to suggest that there was life on Mars. According to Jim Papike " 'It [the result of our research' doesn't mean that they're wrong' UNM researcher Jim Papike said of the NASA claim that the meteorite contains evidence of the possibility of life on Mars. 'But our dad gives no support for that' " (Fleck).
Scientists also have theories about how life might have evolved on Mars billion of years ago. From the pictures and evidence that the probes collected, scientists said that there was no way for life to flourish on the surface of Mars today, but maybe there was life there billion of years ago. This is because the surface of Mars is contaminated with lethal carbon dioxide ice and surviving there is impossible for anything. Scientists' theories said that after the water on the surface dried up, there was still water forming from underground and maybe this was enough for life to flourish there. Two probes called Mariner 6 and Mariner 7 were orbiting the planet when they witnessed what were similar to clouds on Earth. These clouds were formed when the carbon dioxide condensed from the surface.
Hopefully someday these theories might help give us the answer to the oldest question in the world of astronomy, 'are we alone in this universe?'.

My car stopped and suddenly I saw a weird looking alien type of a creature pointing towards me. He told that he has come from outer space. He was wearing his space jacket with a magic watch in his wrist. I was very scared but he was very friendly to me which ended my scare towards him. I was very anxious to know about him and about his world. He told me about his world that his world is full of beautiful things. People there live in peace and harmony. They help each other in need and support each other. Everyone gives values to feelings and emotions and not on material pleasures. I learned many things from him. He asked me to follow these things in my life so as to lead a happy life. He promised that he'll visit me again. After he went away I suddenly woke up and found that it was a dream. Though it was a dream still I would like to follow his words.
