It's likely you're referring to something else, and to help you find the answer, I need more information:
* What time of day/night did you see this?
* What season was it?
* How often did it "blink"?
* How bright was it?
* Was it a single light or multiple lights?
* Was it a steady blink, or did it change color or brightness?
Here are some possibilities:
* Aircraft lights: Planes flying at high altitudes can appear like blinking stars.
* Satellites: Satellites reflecting sunlight can also appear as moving and blinking lights.
* Meteors: These are streaks of light caused by small pieces of space debris burning up in the atmosphere. They are usually brief and fast-moving.
* Atmospheric phenomena: Certain weather conditions or atmospheric disturbances can cause stars to appear to twinkle or flicker.
If you can provide more detail, I might be able to offer a more specific answer!
