Mysterious Balls Of Light

So i have actually seen one of these. Now this being the internet i don't expect anyone to believe me and that's fine. But im just gonna say what i saw. So i was taking a smoke outside of my house in my backyard. All of a sudden this orb came floating from the side of my house! It was kinda close like 21 feet from me, it past me and then after passing me it disappeard out of thin air!!! It was night so i saw it clearly. It kinda looked like in the videos here only it had this white glare to it... I remember just standing there in silence thinking, WTF WAS THAT?? Never spoke a word of it until now that is.
