If Europe had not experienced its Age of Discovery then I think the world would have missed out on globalization and would still be under the age-old regimes unable to thrive politically or advance socially and scientifically.
Explanation:
The Age of Discovery led to multiple explorations around the world. It helped people to know new lands and to explore the different cultures.
If there was no exploration or expansion then the ancient beliefs and monarchy would still be prevalent. Secondly, people would not have known any new land outside their homeland and none of the above stated points would have been possible.
