Beginning the major religions of the world

Today In human geo, we began to go over the 5 major religions of the world.  The first of these religions that we discussed, which happens to be the most predominant religion in the world is Christianity.  This religion was easier to comprehend because I am a practicing catholic, which made this section easier to understand.  One thing that I did find interesting was how vastly the catholic church has changed in the last 50 years, and how there are still churches that did not follow that change. Also, there are more than 2.2 billion people that are Christians the next religion that we discussed was Islam.  I learned a small amount about this religion in the 6th grade, but I still learned a lot.  This religion is more like Christianity than not.  this is because it is an Abrahamic religion.  Their holy book is called the Qur'an.  there are more than 1.5 billion Muslims that fall into the denominations of Sunni (75-90%) and Shiite (10-20%). Most of these people live in Indonesia, the middle east, and North Africa.  They were founded by Muhamad, and they are monotheistic and follow five pillars to ensure that they are living a life in tough with God or Allah.  these 5 pillars are Testimony, prayer, almsgiving, fasting, and pilgrimage.  The third most prevalent religion in the world is Hinduism.  This religion isn't even always classified as a religion and more as a way of life.  They are mostly found in India and Nepal with around 1.1 billion followers.  Their holy book is not truly a book, but rather eternal truth revealed by ancient sages, this is called the Vedas.  there is no distinct founder, but rather many intellectual philosophers. they believe in many ideas such as reincarnation.
