While there are many theories on the origin of UFOs in this post I wanted to ask what others thought about the subject.. So far the common theories of UFOs are they are from deep space, others say they are from under the deep ocean, while others even say UFOs are already here and aliens are walking amongst us..?
What I am trying to work out is which one fits more clearly, also is it possible UFOs are us from the future and the vehicle is merely a time travel vehicle..?
What do you think..? Where do you think UFOs come from..?
