Whatever it is it's not of this world and time.
It was probably the fastest object I've ever seen flying. I was on my home's terrace, suddenly the whole sky became as bright as the day but instead of the white light it was throwing a blue light. Just about 2 seconds and it just vanished. I looked like a circular object with blue lights at it's exterior. And as i have already mentioned it was faster than any flying object of our time. Just like swipe it moved a certain distance in a straight line and it totally disappeared along with the light. The light at the exterior didn't that bright but still the whole sky was lit with blue coloured light. I was speechless, amazed, surprised and mostly curious. Always heard these things in movie and documentary and all now I'm one of the witness.
