Is it possible that a civilisation like ours has already existed?

Since religious belief existed in tribal societies before economic class societies existed how can it be said?

• Since religious belief existed in tribal societies before economic class societies existed how can it be said that Religion is the Opium of the masses and used by the Bourgeoisie to keep the Proletariat oppressed I would like to support Socialism and Marxism and Communism but I don't understand Marxism's views on religion ? http://en.wikipedia.org/wiki/Opium_of_the_people

• Answer:

  I think in today's world this idea is very much out dated. Marx was not a fan of religion but knew it had it's uses, I would look for new theories as these two are dead and more corrupt than the Bourgeoisie they wanted to overthrow.
