Ancient aliens, present time aliens, either way, to dispel such theories as merely belonging in science fiction is to me a naive way of thinking. There are many unexplained phenomena that occur every day in our world and no doubt have occurred in the ancient past. I agree that some if not most of the theories touched upon by the Ancient Aliens are a little outlandish, but it's very entertaining and intriguing to think that if aliens are visiting the Earth in modern times, than perhaps they did also in ancient times when people would be more open minded to such visitation and chalk it up to a religious experience since they could come up with no other explanation.
I for one have seen an unidentified flying object in close proximity, about 60 feet away, hovering with no sound, and the craft was gunmetal chrome without any visible seems or defects. It very well could have been piloted by aliens, but i believe it was most likely some top secret US government craft piloted by the air force. I really never cared if anyone believed me as i saw the object with my brother and best friend at the time. What amazed me the most was not that it could have been an alien craft, but that this technology actually EXISTS! It would be more of a stretch to say that our government has that
type of technology than to say it was piloted by alien creatures.
And no i'm not crazy or some alien enthusiast.
