write a paragragh life on other planets
Answers
Answer:
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 and many scientists and astronomers have come out with many theories about what lies out there and what they look like, if any exist. However, these theories will remain only as theories before someone can actually find evidence of what lies out there. Evidence that the scientists found might prove that humans are not alone in this universe or it also might not be true. 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.” He called the evidence “exciting, even compelling, but not conclusive…I want every to understand that we are not talking about ‘little green men.’ These are extremely small, single-cell creatures that somewhat resemble bacteria on Earth. There is no evidence or suggestion that any higher life form ever existed on Mars.” 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.

Explanation:
☆It cannot be said with conviction that the Earth is the only planet with any life on it because astronomers and space scientists are still trying to look for life on other planets. From what we know of other planets it is however established that life supporting conditions do not exist on any other planet in our universe. To be able to support life the planet must not have extreme variations in night and day temperatures, they must have an atmosphere which has the right mix of gases which can support life etc. As an example Venus, which is closest to Earth, has an atmosphere which is composed of carbon dioxide and clouds made of sulphuric acid—both of which cannot support the type of life that exists on earth. Life is further non-existent because the atmospheric pressure on Venus is very high and temperatures soar up to 450° centigrade. There are small quantities of water on Mars but they are frozen because of the low temperature on this planet. From the above two examples and from what we know of the other planets we can see that, since none of the planets known to man so far have the necessary conditions required to support life, no life has been found anywhere except on the Earth.
