Just Thinking

So I'm just chillin here, the weather isn't the best and I was just thinking of Mars. It might be ridiculous but I do think there is life present on Mars. Yes, there is frozen water on the top, and scientist have said plants have at one point existed on Mars. I'm not talking about that though. I'm talking about living creatures! There has to be some type of extraterrestrial life form out there somewhere. I'm thinking this because who can explain Stone Henge or the Great Pyramids and Ancient Mayan and Aztec civilizations. What ever happened to those cat? It can't be explained. There are things in the great pyramids to suggest that they had help from extra ordinary help in building them. And on Stone Henge, how does man biuld something like this without using simple tools like a pulley or incline? Unless they hd super human people that no one knows about. And finally no one can explian ancient Mayan and Aztec temples. Further more they no one can explain what even happened to these people. So this was just what was going through my mind and I figured I would share it.Yes, you may not agree and I don't want you to be offended by what I'm thinking it is strictly just my opinion.
