Rate the following argument fragment on its writing, argument, and language skills:
Concluding Statement: In conclusion, aliens did not cause the Face on Mars because it is a land form caused by the weather on Mars. If aliens caused the Face on Mars it could have a been more evidence of their existance, and the Face would not look more of a landform. Otherwise, I do not believe the face was caused by aliens, more so of a landform.
