It was very high in the sky and moved at unbelievable speed.

I was on the Goliath roller coaster at 9pm hour and as we approached the first drop I looked up and I saw what looked like a star (light) come to a sudden stop. It was already in motion when I looked up but I thought maybe i was imagining the movement. I remember thinking "what is that"? Then it moved impossibly fast in a sw direction and came to another stop for maybe 1.5 seconds. And then it did it again this time slightly changing direction (s) and came to a stop for another second. By then we were going down the first drop but I was totally ignoring the roller coaster while going down forst drop wherr insaw it move again. but I lost track of it since there was a moment of going into a tunnel at the bottom of the first drop. I could see that it wasn't just an orb but that the light was part of a craft. It was very high in the sky. I would say it was at least as high as one of our highest airplanes that look very small in the sky. Yet the light was still about as big as we see on of our planets in the sky from our perspective. It did not get brighter as it moved from stop to stop, no noise. It just moved across the sky without even a streak or trail of light as it moved. And it moved impossibly fast and unlike anything I have ever seen or heard of. It was fast enough to know that if anything was inside the craft, it would have been devastated by g forces. Im 38 years old and have seen alot of things, i never imagined i would ever see something like this. Therefore I am convinced that either we, humans, have secret anti gravity tech that would neutralize g forces, or there really are visitors from outer space.
