Is the Earth an Experiment? Were we "planted" by the aliens here?

Is the Earth an Experiment? Were we "planted" by the aliens here? It might very well be that the Earth is a bigger Australia where Aliens put their criminals to get rid of them. Is the Earth the biggest prison camp in this universe? In the beginning I believed: "That cannot be" After watching this video I changed my mind, as the evidence offered is stunning and I wonder who were my ancestors. Were they from this planet? Or maybe from somewhere else? You may not believe me, but listen in this video clip to these people speaking to the public and also the former UN official. Are these people all liars? Or are the whistle blowers that we ought to listen to ?
