The Germans started experimenting with alien tech in the 1930's and since then the US (after basically kidnapping all the top scientists) stole the technology. We the US are responsible for 80% of the UFO sighting worldwide. Some of it's Tesla based & some of it from reverse engineered alien tech. We now have colonies on the moon & mars which are basically funded by the super elite, we also have hundreds of underground bunkers also funded by the super elite. The day to day citizen will be left to fend for ourselves while the powerful people either head off world or underground in the event of an impending disaster. There is a planned thinning of the population going on right now & when it's complete only the super elite along with top scientist re-populate this planet.
