Most constellations are circumpolar. Over the course of a night they appear to rotate around the North pole and so do not identify a specific direction. As a reult they are of little use for navigation.

in theolden days, many sailors usedd the North star and the moon to guide them
The first constellations were, we believe, invented by the ancient Babylonians and Sumerians, and perhaps the Phoenicians. These were to give people a way to refer to the stars and constellations, and provided a heavenly anchor for their stories. Most of the northern hemisphere constellation names that we use today were invented, or adapted, by the ancient Greeks and Romans. The southern hemisphere constellations were largely named by sailors and mariners. It's likely that the people who lived in these southern lands had names of their own for the constellations and stars, but few of those are still in use.

If you know the constellations and stars in the sky, you can use them to help you navigate. Sailors do this by knowing which directions stars are positioned. They can then tell which way is north, south, east and west.
