light appeared/turned on and traveled instantly many miles. not sure if it turned off or disappeared due to distance

Driving south on 4910 E County Rd 64 and suddenly a light appeared several hundred to thousand feet above me. My windows were up and I was unable to hear anything audibly. Also, there was no visible lights leading up to this point and I had been on the road for 1/2 mile, since the nearest exit (278). The light instantly travelled in the straightest of lines thousands of feet to a couple of miles before turning off or disappearing. All of this took place in less than 2 seconds. I've seen hundreds of shooting stars and this was nothing like it. I jokingly told myself it was a farmer with a drone observing his fields. After dinner, I found articles talking about the mystery lights in Eastern Colorado that people have been reporting. I've only lived her for 2 months, so I had never heard of such. One of the articles mentioned this web site and I am her to make a report. There is no way this was a shooting star or a drone based off of current known technologies due to the speed it traveled.
