text: To conclude this argument, you could still go on saying how aliens are real, and how they created this landform. But in reality, no one has the facts to prove that an alien life-form had created this landform. No one has the facts to prove there are alien civilizations on Mars. I only say this because there has not yet been facts, or any information involving alien-life forms or ancient civilizations on mars. Maybe in the future, there will be signs of some type of life-form on Mars, or very odd, peculiar objects that we may find somewhat weird, or, out of the ordinary. It is only, but a matter of time before NASA does find something very odd and out of the ordinary, on any planet, in our solar system.Would you want to be forced to do an extracurricular activity? It would not make any sense for our principle to force everyone to do an activity after school. It should be our choice on whether or not we want to do one or not. Also for some kids it may be hard to fit one into their schedule, they may not have transportation to and from the activity, or they could just not want to do an extra activity.
