Rate the following argument fragment on its writing, argument, and language skills:
Concluding Statement: If aliens did make the artifact where are they? Wouldnt we see something about them or some weird signals coming from them? Aliens dont really exsist, as much as the subject wraps around our brains, it really leaves us clueless on what we know and what we dont know. Since we really have no proof, I believe that aliens did not make this artifact, found on Mars. I could be wrong to some people, but i believe my claim is true. There really may be a civilization on Mars if we could really think about it and further our studies. But for now i believe this artifact is really just a weathered rock on the face of Mars.
