What kept europeans from discovering unknown lands?

Several factors hindered Europeans from discovering unknown lands before the Age of Exploration. Limited maritime technology and navigational skills restricted long-distance sea travel. Additionally, prevailing geopolitical concerns, such as feudal conflicts and the focus on land-based trade routes, diverted attention from exploration. Lastly, a lack of knowledge about the vastness of the oceans and the existence of other continents contributed to their hesitance to venture into uncharted territories.
