Here is an excellent video series about UFOs. If this video is true, than you will have seen a real alien being...commonly known as The Grays, either from Zeta Reticuli or Orion. I do not know if it is true or not though, but I always tend to keep an open mind.

To my knowledge, these aliens are malevolent and seek to dominate mankind. They really want our genetic material to save their own race. This is why they clone because they cannot reproduce naturally...ie internal technology.
