Rate the following argument fragment on its writing, argument, and language skills:
Concluding Statement: In conclusion, the face on mars is supported and not supported. NASA has proven with photographic evidence that it is just a natural occurance while conspiracy theorists say that it is a martian civilization. I think that NASA's facts are very believable, and they have the science to back up their claim. I hope that in the future, more people will base their beleifs off of science and not fictional conspiracy theories.
