Europeans first embark on exploration to the East as they looked for trade routes
Europeans had to find new trade routes to the East because the Ottoman Empire controlled and taxed existing routes.

Therefore, in order to continue trading with East Asia without trading with the Muslims, the Europeans would need to find other routes to East Asia. The search for these routes culminated with the Age of Exploration.
