What factual evidence obtained from the surface of Mars, supports this theory?
What meteor impact has been observed on the surface of Mars and recorded with scientific instruments?

Your reply was actually an Aristotle style thought experiment, simply because Aristotle said that stones could not fall from the sky. It also contains no objections of any substance. Has anyone seen a glacier on Mars? No. Has anyone seen a volcano erupt on Mars? No. Has anyone seen impact craters on Mars and attempted to attribute them to volcanism? Oh, yes, and they were dead wrong.
