Would we currently be at this point of civilization without religions?

[brewer]

As much as I hate all the persecutions, suffering, and general nonsense that religions have brought. upon people, and truly believe that pure humanism is the way to go, how can we know for sure that without the existence of the current major religions and its contribution in bringing stability in the past, we would be living in a much better, utopian world?

My underline.

Time travel, take out the major players as the come up. Come back and see.

Make two sims, one with and one without (I know that this will trip some triggers here). See what happens. Even this is not a sure thing, a guess.

Find a culture with no religion ever (not sure that exists, maybe ask  historian Min). Do a comparison. Still a guess.
