Evidence That Aliens HAVE Visited Earth

The world is most certainly divided on whether or not aliens have actually visited earth. It’s undeniable that there are things on earth that are very difficult to explain, and seem almost impossible to have been completed without the help of an external force of some kind. More than 40,000 Americans have insurance against alien abduction and most British, German and Americans believe in an intelligent lifeform of some sort, makes me wonder, what do you believe? Today we look at archaeological and other evidence that could lead us to believe that they have spent some time on earth at one stage or another.
