Answer 2

Hii mate here is your answer

some of our friends at the Lakeview museum of arts and sciences in peoria illionis wonder wether there is life on mars this is an idea that has intrigued people for centuries and one that i perhaps like you have wondered about for most of my own life.

Earth is the only place that we know for certain supports life . many claims have been made by observers who thought they saw evidence of life on Mars but we know they were tricked by the very difficult measurements we just cannot see enough detail on mars to answer this question . we need a close up to look at this planet.

Because there is no oxygen on mars.
