If you look at the fossil record, death rituals occur as the size of the cerebral cortex expands - the cerebral cortex is the part which governs our ability to figure out cause and effect. This shows spirtuality is an evolutionary trait! And the brain functions that allow us to do science, figure out how things work, and make revolutionary advances are the same ones that allow us to conceive of gods, spirits and so on.

Furthermore, organised religion is key to unite large groups of humans who have no blood connections - as you had in the early cities around the Neolithic Revolution. Organised religion is key to unite us on a large scale, so religion also led to the birth of civilisation as we know it.

So a world without religion is one which lacks 'humans' - homo sapiens - as we know them.
