No! It's not the invasion of some extraterrestrials from another planet, it's right here on earth.
As you may already know, and I will use the words here as illegals, refugees and foreign nationals are still crossing our borders.
The number, as reported as of April 2014, may be hundreds of thousands who have entered the country already. Some are fleeing from oppression and other reasons. Some that have crossed the border could be terrorists.
Our technology today exists that it is possible that our government can hear and see what someone does even at home.
Don't be surprised or alarmed if you see some strange object in the sky. It's probably a drone heading for some secret operation, or maybe even observing you.
