Rate the following essay on its writing, argument, and language skills:
An unusual face was spotted by Viking 1 in 1976. Looking at evidence that were provided, it shows that the "unusual face" found on Mars was just a mistake. Even though they had picture of the unusual face the first time they spotted, it was a really blurry one so it created illusions for people to make it look like there was actually a face on there. It was later proven by Mars Global Surveyor that it was just a natural landform on Mars using photography. Therefore, pictures don't lie which makes the "unusual face" just another natural landform.

In 1998, the Mars Global Surveyor flew over Cydonia, where the unusual face was found, to snap a picture of the unusual face which was ten times sharper than the Viking photos. Since the picture was pretty clear, it reveal what was actually there on Mar's surface. It proved that it was just a natural landform and that it wasn't any alien monument. People may say that since it's winter it was the cloudy time to of the year of for Mars so other things such as clouds could've had an effect on the picture but it doesn't change the fact that it's just a landform no matter how unsatified the people were.

In addition, NASA unveiled the image saying that it was just a huge rock formation. They noted that it resembles a human head because of the shadows. It was creating illusions for human eyes so they didn't see the actual object but instead they saw a face on Mars. Although, some scientists believed that the face was an alien artifact which was what got Mars Glbal Surveyor to even begin taking pictures of Mars to prove that it was just a natural landform. Overall, the face on Mars is just an illusion even though some people believe it's real.

However, people might think it's real. Looking at the evidence provided by the Vikings which was the first photo of the face on Mars, it really resembled an Egyptian Pharaoh. Even a few scientist believed that it was an alien artifact and it even became a pop icon. It was starred in a Hollywood film, appeared in books, magazines and radio talk shows which mean people actually believed it. The face on Mars attracted many people's attention. Which is why people could say it's real since the majority believes it but what really matter is how it's proven. It was proven using a camera that snap pictures clearly. Everyone was later informed that it was just a natural landformed because of the picture taken in 2001.

In conclusion, the face found on Mars was just a natural landform that looked like a face because of a blurry picture taken by the Vikings in 1976. Many scientists and people believed that it was real but it was just an illusion to the human eyes. In 2001, Marlin's team took a snap of the face on Mars which prove that it was just a natural landform. Garvin compared it to the landforms on Earth so that people could understand and believe that it was just a natural landform. Therefore, the picture taken in 2001 was an evidence that proved that the unusual face found on Mars was just a natural landform.
