I can't wait til they finally release more of what they know about Mars. I'm pretty sure there's something alive (by our standards), cuz even now on Earth we're finding species of like, extremophilic bacteria and archeae that withstand mindboggling conditions we never thought of - who can say there aren't strains like that evolving on Mars or any other planet out there. *_* I'm so excited. I love the idea of terraforming Mars although some part of me is terrified for it to happen. Think of all the shit we could find on Mars. *_______* I'd go there in a heartbeat.
I think it's awesome! I believe there is life at a cellular level like @KDA20 stated. As far as other life forms like what we have on earth vanishing it is a possibility. If there was I'd like to know why they disappeared. :/
It doesn't really surprise me, I mean it has ice so why not water. but I don't think there is any life or if there is it is only bacterial. which could mean two thing. 1 we are seeing a planet past its life bearing days, 2 we are seeing it before. I think it is number 1
