I saw two UFOs so I have accepted they are real. I am an engineer and saw two while I was in the Army. I was very well versed on what type of aircraft we had and what is possible. One of the craft moved in a manner that is beyond what is possible with what I know of acceleration and physics. That being said, bigfoot is my passion. I wish instead that I saw a bigfoot. I have met people that swear by ghosts so I remain open to them but have no personal experience. The funny thing is I am the biggest skeptic you will ever meet. I just ended up more skeptical of the scientific orthodoxy that laughs at the possibility of these phenomena
