Rate the following essay on its writing, argument, and language skills:
Life on Mars has been discussed for many years. The face on Mars has raised the concern on whether there is life on Mars.\ Most scientists believe that there is not enough evidence to show that there is infact life on Mars. Common people ,who disagree with scientists and other people who agree with the scientists, think there is enough evidence for life to be on mars. Life on Mars has been a very contradictory argument for many years. There has never been 100% true evidence of life on Mars. Many people just want to believe there is life.

First of all, the face on Mars has never shown any pure evidence that there is alien civilization on Mars. No on has ever been on Mars' surface to check around the face to see if there actually is pure evidence to support alien existence. If life does exist on Mars, we probably would have more evidence than we do now.

Next, for many years NASA and many other scientists, or even the common man, have been debating whether there really is life on Mars, or used to be. All of the pictures that scientists have now show no sign of life. If there was life, we probably would have noticed more structures around the face by now.

Finally, The main reason there is a debate between common men on whether there really is life on Mars is that they simply just want to make themselves believe there is life on Mars. The convince themselves there is life. They still have no scientific facts to support their claim.

In conlusion, the face on Mars is just a natural landform. If there is alien life on Mars, then there is no 100% pure evidence that there is or ever was. These are the reasons why life on Mars does not exist as we know of at the moment. But there could always be new evidence that says otherwise.
