text: To start, the idea that at one point in time there has acutally been life living on that planet is crazy. In paragraph four, it talks about how at on point there may have been big oceans like that are similar to the ones on earth. We think this because there are many rocky surfaces, such as valleys, mountains, and craters, that can only be formed from water eriodication. When you even look at it, it just look earth like. Obviously it has changed over the years but you can't rule it out. Is it possible there were living things on this planet at once?
