Why the emergence of islam in the seventh century ce can be considered a turning point in world history?

            The impact of this religion has and still is affecting humanity.  Due to the nature of written religious texts, people inherently interpret them how they see fit.  During the time of the crusades was the first major event that Islam was a part of.  Judaism, Christianity, and the Muslim religion all considered Jerusalem the holy city, and all wanted their religion to have ownership over it. This was a bloody time for humanity, and it was all based around battling over holy land. Muslims still kept their holy land and to this day remain the most populated religion in that region. The next major historical event happened many years later when a bunch of radicals Muslims flew into the world trade centers. This was the story we are told, no one knows for sure exactly who bombed who, there are many theories that the U.S. government did it so they had a right to go into the Middle East for oil. Either way, the story goes that these extremists crashed plains into the twin towers and the pentagon to show that they were not happy with how American functions. This created a war between the lands that is still going on today.
