Aliens vs Predators vs Homo Sapiens?

I gave this question a deep thought and I have determined that we are not alone in this world.  Supernatural occurrences happen more often than we think but the government does the best job and hides all the secrets from the public.  Local legends such as Big Foot, the Lochness Monster, aliens, and other mythical creatures all have ties with the government.  For instance, if aliens did not exist, why would Area 51 not be open to the public?  Why would it be created in the first place and for what purpose does it truly serve?  All these unanswered questions are based on the paranormal and cannot explain by logic thinking.  Yes there are doubters out there who do not believe in such activity because they are the type of people who follow the order of the law, they do not think outside the box, and they put full faith upon logical reasoning to explain reality.  Although we may not know it, we are not the only species that are unique in the time and space continuum.  We could all thank our beautiful government for doing such a good job and keeping secrets from the people and the entire world.
