Most sightings have been in the southern US. Although I consider myself a believer and am open to the fact that there is something out there, most sightings are just for publicity. The whole "Monkey see, monkey do" thing. However, ancient civilizations and many Egyptian artifacts have also recorded strange phenomena with writings and drawings on the walls. To research further, I recommend you read the book, Chariots of the Gods. It contains everything I have mentioned and more, leaving you open to make your own decision in whether you believe or not.

Many people claim to have seen UFOs.
Yes.... People have seen UFOs.
UFOs are spotted all over the world. Less developed areas of the world with less light pollution.
The desert of New Mexico seems to be a hot spot for them.
Not a single. Not proved presence of UFO
UFOs are very often seen on Earth, and nobody knows what is inside of one. If there are truly UFOs from space, when they supposedly come to Earth they may already be learning from us.
Hundreds of UFOs are reported every year on every continent of the world.
