The shapes of the rocks tell you they were transported and the size of them tell you that wind didn’t transport them. The shapes also tell you that the stream was flowing for a-long period of time and not just a couples years. NASA is finding materials on mars that are potential ingredients of life. The reason why the stream the rover has found is good because a stream could be habitable environment, which potentially means signs of life.

People for years have been wondering and asking themselves if there really is some sort of life form anywhere else in the universe. I mean, the universe is huge so why not? Knowing that the NASA Curiosity Rover has found evidence that there once was a stream flowing vigorously across the surface of Mars.
