Do you think aliens in ufos have visited Earth? (And all things UFO)

I still can't believe any of this is true. Seriously, I can't. Even with all the circumstantial evidence, all the reliable sources, I am still not convinced. Not that I don't want to be convinced, I do. But, and I think most people share this sentiment, I will not believe it until I see it, there's something in my mind that just won't let me.

If we see it, actually see it, real proof, then what it will do to our world, we really don't know, do we? Maybe almost nothing perceptible, hardly a change, but maybe it will have a massive impact, if for no other reason than it should encourage humanity to dream bigger and better.
