How did Muslim contributions impact the world?

Muslims have played a huge part in world history, they had many land based empires that over the years only Rome and China could compete with, they held control of a huge portion of trade due to their position between Europe, Africa, and East Asia, if not for their retention of the knowledge that was discovered during Persian, Greek and Roman eras, the U.S.

might not have had much of a basis for any of its founding principles, and finally their religious beliefs greatly affected development of many countries such as those in southern Europe (Spain and Portugal primarily), Africa (mostly northern such as Egypt), Middle East, Southern Asia (India, and even more so Pakistan), East Asia (they had a thing in China for a while that affected Neo-Confucianism),

Southeast Asia (Indonesia is hugely Muslim), and Northern Europe and the Americas as listed earlier. I just listed just about everywhere on Earth except Australia and Antarctica, so the Muslims have had a huge impact on the world. If you want any more in depth, I'd suggest some personal research or asking a professor, hope this helped!
