Yes and it has been for approximately 6,000 years. Religion was first used as a way to organize (ie control) people enmasse in ancient Sumeria. The origins of the three main belief systems (that I think of as prefabricated mindsets) that exist today: Judaism, Islam and Christianity, can all be traced back through the myths and legends of the Egyptians, Babylonians and Assyrians to the Sumerians. There was also, of course, a large input from Greek myth as the the writers of the New Testament were all Greek speaking individuals. This is why the Christian concepts of Heaven and Hell closely resemble the Greek Arcadia and Hades.
The truly sad thing is that not enough people - living today - have woken up to this historical reality. A great many people are still controlled by mindsets that were first fabricated 6,000 years ago. They cannot see that they are being led into a war: between Christians and Muslims, that is going to kill vast numbers of people. They think that they will be fighting this war 'for' their religion. They won't. They'll be fighting to make rich people even richer. They will be dying for a lie and dragging the rest of us down with them.
