You go to sea only because there is pole star. Without that no one goes, because of pole star people started sailing I would say, as they know there is one guide. I don't think any one sailed without the knowledge of pole star, it's basically as essential as a ship to sail in unknown waters... Of course later compass came but pole star still matters as a source of truth
