This was not man made, or was it?

So a couple days back i bring my 2 kids, and wife out to our front balcony to eat dinner. It was a clear night. No clouds, or anything. You can see the stars so clearly. Which is rare in the part of New York i live in, but that night was beautiful. Anyway I live in an area where there is lots of airplane, and helicopter traffic, and not to mention lots of fighter jets, and military choppers, because there is a military airport close by. Over the many years here i've seen fighter jets fly over, choppers roar by, commercial planes, and copters pass over, and even an occasional stealth bomber quietly float over the house. My kids get excited every time they see any of these things. So we're eating, and my daughter yells for me to look at the plane, and at first im like ok, eat yr dinner. She insists over, and over i look up, and in my mind im like how ******* llong does it take for a plane to pass over, and i look up. It was the brightest light i ever seen. I know it wasnt military, because i've seen how high those planes can get, and this was way higher thanything i've seen, and yet still way bigger if my daughter, and i could have seen it so clearly. At first i thought it was a star, but it was moving extremely slowly accross the sky. At a point it could have stopped. Im not sure, but once it started moving again this thing was faster than any plan or copter i've seen, and i swear to anyone, that at the distance that thing was from the ground it should not have been seen without a telescope, and the light would have been so faint to almost nothing had it been a man made plane, but it wasn't. It was almost as bright as the sun would be, but white. Whiter than anything i ever seen. I know this thing was huge, because the ratio of its size to distance. Does anyone know what this all could have been? Im paranoid after that night.
