Mars is the fourth planet from the sun and since it is now 2016 it was about 40 years ago that a face was found on the planet. Some people think it was made by aliens and other people are logical and say it is a natral land form. I think it is just a land form because you can duscern things in a digital image 3 times bigger than the pixel size, we havent found anything else, and it look like some of the landforms here on earth.

First of all, in paragraph 11 it says that as a rule of thumb, you can discern things in a digital image up to 3 times its size. This helps prove it wasnt made by aliens because they cal close in on the picture and they didnt find anything else around it like other sculptures or houses or anything. therefore, it was either really old or just a land form.

Also, we haven't found anything else on the planet. If aliens made that dont you think they would have made other things and if they did wouldnt they also be there. It is not likely the face is an artifact because there should be more and if it was made by aliens and they had more it is unlikely that they made them and only that one is still there.

It does look a lot like what the agyptians made so if there were aliens they would probably be capable of doing that but it also looks like some of the landforms we have here on earth. Garvin even says in paragraph 12 "It reminds me most of middle butte in the Snake River Plain of Idaho. hat's a lava dome that takes the form of an isolated masa about the same height as the face on mars."

In conclution, It is just a natural landform that happens to look like a face. We havent found anything else on the planet and the ppicture doesnt have anything in it like a home. Also it looks like some of the landforms here on earth, we have some natural things that look wierd so why cant mars? The face was not made by aliens.
