how did the renaissance learning lay the foundation for expoloration

so all of the explorers from back in the day went exploring around the world for instance like Columbus. he was actually Portuguese but anyways the renaissance put a lot of ideas into there heads, i guess you could say that there was a lot of conspiracy's i suppose that made them want to explore. so because of Aristotle and Galileo and other people like that they all wanted to start exploring so they all did. but a lot of explorers didn't succeed though.
