I was surprised to find out that scientists actually think there were once Martians on the Red Planet. I definitely think there is erosion on Mars because of the countless valleys scientists have discovered. I also think there is erosion on mars because of the annual rainfall. If all this is true, The Red Planet may have been the Blue Planet after all.
