UFO. how do people still deny their existence?!

The aliens will come in 2012..
GOD has been disproved as alien visitors throughout the years..
The Government is planning to have a farce invasion 2012 during the Olympics.. I think thats when It would make the most sense for the aliens to come.. expose the government.. make the world know what they have been up to..
They aren't going to come for an invasion. so don't be afraid. 
they have come before.. they came to give us knowledge to further our existence and help build our earth.. we shot at them and tried to destroy them.. we are twats...
If they wanted to destroy us.. they would have by now..
I think they brought us the moon, so we would have life on this earth.
I believe we are an experiment..
