I, personally, find it pretty tough to believe there isn't any other form of life out there. Intelligent or not, I'm convinced to believe that there's at least one other life form somewhere, be it space giants that were once native Americans and flew off, coming back to teach us how to make super corn, or little sea-creatures or bubbles of amino-acid that has a mitochondria, or for even just a ******* shred of grass.
Lots of UFO sightings, odd amount of cover-ups, odd amount of "coincidences" to us.
"Coincidence" as in lots of references in the egypt hieroglyphs (that are slyfully unfilmed! ) Many mythological sub-meaning. ( I recall one that said like there was this Giant golden egg and brought forth humans out of it. Now being a myth, it has roughly the same creditbility as the bible (Offence ><!) But Golden egg out of no where and came to earth? Mothership? (Odd but maybe not) The references are unlimited.
After we unleashed the first nuclear bomb Ever, what happened? The amount of Alien sightings happened, and Supposedly LOTS more reports. Even Commercial Airplane Pilots sometime report them. Why is there suddenly lots more spottings by lots more people?
After ross-well(sp), alittle time after that incident, we have the coming of the first electronic computers.
Odd eh? We were just discovering Electronic computers after that ( And stopped Giving Heroin Cough-syrup, lol, funny thing is that it actually stopped coughs!). Isn't it abit odd? The other inventions at the time happen to be also: Hardware for computers, Jet engine, Idea of a Nuclear reactor, and missiles, pretty much a Scientific Boom.
I believe.
As for the cover-ups, who knows, probably government wet-work or something. (reverse engineer some stuff to get us all the neat stuff we can have! ^_^)
