So, I have been doing some thinking and have come up with my own theory about UFO's. My theory is that they come from deep in our oceans waters, and have been there since before humans were even around. There have been so many sightings of UFO's going in and out of the worlds oceans, and are being called USO's (Unidentified Submerged Objects). Now hear me out here, my reason for thinking that we have an Alien civilization, which is not alien at all, is because think about what was the first forms of life. It was fish, and other sea creatures. I happen to think that since there were around billions of years before us that they could have evolved into an intelligent species long before humans ever took their first step. It makes sense to think that something that has been around billions of years before us would evolve before us. Plus, our world is 90% water, and we havn't even explored a dent of it. Anyways, any comments?
