Aliens

Is there really life on other planets? And if so how long has it been there for? 75 million years of the most credible alien evidence here on Earth: from the age of the dinosaurs, to ancient Egypt, to the skies over the western desert in the present day US, ancient cave drawings of strange creatures, an asphalt-like substance in an Egyptian pyramid made from the remains of unidentified creatures, continued mass sightings in the US.World governments should prepare a co-ordinated action plan in case Earth is contacted by aliens, according to scientists.They argue that a branch of the UN must be given responsibility for "supra-Earth affairs" and formulate a plan for how to deal with extraterrestrials, should they appear.There is a strong belief  about aliens they are exist in the United States. Simon Conway Morris, a professor of evolutionary palaeobiology at Cambridge University said, is likely to be Darwinian in nature. And he argues that life anywhere else in the universe will therefore probably have important similarities with life on Earth – especially if it comes from Earth-like worlds that have similar biological molecules to ours. People see so many UFO’s are widely seen around the world .Even more widely around the U.S. more closely around areas near Area 51. Then US really hiding aliens? Area 51 has got to be restricted for something. In that military base, according to  bibliotecapleyades.net, there are over 30 levels that are above top secret. For many years now, area 51 is so restricted that not even the president is at a high enough rank to enter without someone keeping an eye on him. If Aliens are real! are they being hidden from us all?
