Bright Starlike Orbs Slowly Move down to 50-100FT. Above Earths Surface Without SoundWe were at the Westwind Drive-In, in Concord, CA, when as we were waiting to have our battery jumped, I had nothing better to do, but to look up at the aircraft that were coming in for a landing, or just taking off, as the drive in is located right next to the small airport, when I noticed two starlike objects that were just hoovering about 200 feet above the earths surface and heard no noise. After getting my vehicle started, I left and entered Hwy. 4, as I got into the slow lane, one of the objects moved down to about 50 feet above the freeway and once again, I heard zero noise and it appeared triangular, with three points and was just one color and extremely bright, white light. Then, as I began to move down the freeway, towards Brentwood, these two lights, moved back up to about 300 feet and began pulsing, and even having flashing red lights, my children were in the car with me and saw it too and began getting scared when we saw the triangular shape and heard no noise whatsoever! These continued to travel down Hwy. 4, until one finally settled, hoovering at around 375 feet, at where appears to be downtown Bethel Island and the other, at about 150 feet above the old farm that is at the end of Sellers Avenue, near Iron House Elementary School. I have seen these things turn into a grey gassy orb as well, but these seem to just go back to being singularly bright and hoovering. I guess besides wondering what these things are, where they came from, and what they want with us, I guess I'm just wondering why the United States Government isn't doing anything about this! I've seen all sorts of videos on You Tube that have these exact things in them all over the world, the videos that are the most puzzling to me though are where NASA astronauts saw these things a long time ago and is being told by Houston to just ignore them. Can these things hurt us? This isn't my families first time seeing them and there really isn't anyone ! to call to report it to, with the exception of the local polic! e, who w ill more than likely think that you're some sort of nut. I've had four adults and one child in my family see them now, that have always believed that besides GOD, that we are alone and did not believe in any sort of aliens! We now know that we are definitely not alone and are beginning to get worried, is anyone else? I feel like I want to start some sort of chapter or something, but am not sure how much good that would do, it doesn't appear as though we would have any sort of defense against these things anyway, if they should become agressive at some point!
