Extraterrestrial Intelligence

I believe we are being visited by extraterrestrial intelligence everyday, but they just haven't presented themselves to us. It's obvious that we don't have anything that they want because they would of been taken it a long time ago.

So the question is what exactly are they doing here and why won't they present themselves to us?

I personally think they're observing our planet just like we would do if we traveled to another planet. If we found other life that were way less advanced than us, we would then do all type of sick experiments that you see these scientist do today. You can also conclude that aliens that visit earth had some type of contact with another group of intelligence at one point. I think that it would be difficult not to make contact with the first other intelligent life in the universe .

Life forms from other planets may not want to present themselves to us simply because we're are not ready... Take a look around you and see how we treat our planet earth. Intelligence from other planets may very well be advanced beyond war and we're certainly not.
