You need a fairly loose definition of religion, to make that stick - and even then, quite a few atheistic societies seem to have tooled along OK.
And contrary to the claims of theistic oppression, some of the ones who do are right to.
Like some dogs want the leash, some want off.
The one size fits all model of the good and the soul has no more claim on sane allegience than Procrustes Bed has on the fellow traveller.
When I hear of a society that has survived even a tenth as long without any spiritual investment, I may take that seriously.
