Do you really think they have listed all probes and satellites they have sent? Do you think space travel is a new idea? Do you think Soil Samples have not been analyzed by machines we send out? Yes, I do believe in Conspiracies as in the Literal definition of them. I do believe our governments and unknown entity's have withheld and covered up information for Centuries on these Subjects. A Real Scientist would already know the government hides stuff because he is on the governmental pay roll. Where do you think Grants come from. Ancient Astronauts are not what i am referring to i am referring to a much more blasphemous past with these things.
