As people built more efficient communication systems and more complex governments in early agricultural civilizations, they also developed what we call religion today.
After doing some research on the common features of early agricultural cities, I am interested in finding out why all civilizations adopted some form of religion and how these religions spread over large regions. I know that by 1200 B.C. there were developed cities in most parts of the world. After studying some early writings from Sumer in Mesopotamia, I know that people devised gods who looked after themselves and the well-being of their crops and cities. But the world religions I know of ;
“Hinduism, Judaism, Buddhism, Christianity and Islam” were bigger than a single city or a single region of the world. In fact, these religions have existed for thousands of years and all seem to have developed at the same time.
So why did several large-scale belief systems emerge between 1200 BC and 700 AD?
Why did all the major world religions emerge during that period and Why did religions globalize?
