that thing was glowing and floating peacefully in the sky and the light was white in colour.it was 7 pm and dark already. me and two of my friends went someplace silent, we were on our holidays so it was the only time we met, we don't drink(to make it clear). we were having conversation. I always look up at the sky and the stars(I like looking at the sky).it was cloudy that day and windy too, felt like it was gonna rain. and while I was looking at the sky I saw a light behind the clouds. it looked strange because the light of that thing was spreading and contracting ( like imagine a circle expanding and contracting now imagine that circle as a sphere of light). immediately I tell one of my friends to look at that thing he sees it just for maybe a second while my other friend was not able to have a look 'cause that thing disappeared behind the clouds. the friend who saw it have no interest in ufo's he is religious (Christian) i am not the believer or non-believer of ufo, somewhere in between . we soon start making fun of ufo's and aliens.the movement of that thing was so smooth it wasn't abrupt like most ufo's. I would say it was floating peacefully.also the light was white like milk.I don't know what that thing was but that was definitely not a plane. i would just like to report and know whether you have an answer.
