It is very curious how some people deny the fact of space exploration, prediction of science on different facts, for it being "too complex and difficult to even be possible".
Which can be seen on many online blogs or subsidiary comments. Yet they don't even give a second thought to the fact that they're expressing their ignorant opinion through a machine, which has the capability of uncanny accuracy and precision to manipulate single electrons to operate billions of mathematical calculations per second inside an one inch by one inch piece of silica and gold, through that specific calculation pattern those are turned into graphic information by thousands of tiny lamps or individual pixels working in perfect conjunction. This machine consumes much less energy than a light bulb, and is connected via electromagnetic waves to a globe-wide network of information, contained in millions of synchronized electronic discs or solid state drive, which store and manage almost unintelligible amounts digital data. Those machines are powered by streams of electrons which travel kilometers inside copper wires, from their source in a facility which transforms the many forms of energy in nature into usable electricity. All this seems negligible, but shooting a missile into the sky with enough accuracy to come close to another planet seems impossible. Who gets to understand them?!
