I am of two minds on this subject, one is that there is always something out there thats is unexplainable. And the other is that there is always someone out there that likes practical jokes.
I have seen lights in the sky that can not be explained and the way they moved off at different angles away from each other can not be explained, but i do belive that we are not alone in this vast universe either.
Here's photo with a little editing......shows two of them now......
We use to make those while out in the desert and watch everyone freak out. You simply get the clear laundry bags (which contain your clean clothing from the cleaner's) and tape two pieces of balsa wood in an "X" to the bottom. Glue a small votive candle where the stick cross each other and light it. The heat fills the plastic bag, causing it to rise. For even a better effect, use fishing line and string several bags together and they will climb thousands of feet in the sky, and will swirl around as it catches the wind. The candles also illuminate within the bag, causing a glowing effect.
I realize it is very easy to fake such sights, but I don't think candles and plastic bags disappear (well, except when they burn out) and just appear in the sky without "floating up".
Or move against the wind. Now I don't have the atmospheric data for these supposed sightings, but others that have ben investigated travel without regard to the wind speed and direction....which plastic bags and candles do not.
Not saying these latest videos are real or hoax, just saying others have not been determined to be cheap dimes store tricks. Which makes them fit the definition of U.F.O. 's
while I have never seen one, I do believe in aliens. there are so many accounts of similar looking creatures from every walk of life and every corner of earth, how do you explain it if it isn't alien life? I watch a show on History Channel called "Ancient Aliens" it is very interesting.
