Sure I can name a time period.

The future. Fair enough?

Back when people lived in caves, or mud-brick huts, or navigated by starlight people didn't know any better than to assign magical properties to imaginary beings that controlled the world.

To them ascribing supernatural events to divine intervention was just as logical as ascribing them to plate techtonics, the rotation of the Earth around the Sun, or geothermal activity. But as time has passed and society has developed, science has also progressed and can now explain more and more of the natural phenomenon of our Universe. Religions still cling on where they can but they have nowhere near the control over people they once had. Most Americans claim to be part of a religion, but for most it's more tradition than any kind of real, unquestioning faith in supernatural creatures.

People don't need God to explain anything anymore, at least not in the developed world. Some people still use it as a hedge against death by buying into the pretend religious nonsense about eternal life, the soul, heaven, hell, and all that other mumbo-jumbo.

That'll soon pass. Every generation gets further and further from the myth.

In the developing world things are different. People don't have shit so they still rely on religion's "promise of a better future" schtick and consequently a lot more people are a lot more serious about religion as they have more of a vested interest in it. But the developing world is only developing in one direction - into the future.

The scientific and technological revolutions really only kicked off in the 18th and 19th centuries. Humanity has been around in its modern form for 200,000 years. Since before recorded history, going back as far as the oldest known cave paintings and neolithic "virgin" sculputures, humanity has shown a reliance on religion to a least some degree. It very likely that the pathology is much older than that.

So for at least 35,000 years but most likely much longer God had been meddling in man's affairs. In the last 350 years God has moved out of the palace, out of the statehouse, out of the courthouse, out of the classroom, and out of the central position it had occupied for mellenia.

Gods, and religions along with them, have seen their heyday and are on their way out. It isn't going to happen overnight, but I never suggested it would happen overnight.

I said it's going to take thousands of more years for it (religion/god) to be purged from all modern reference. Religion will still leave its imprint on our culture, for better or for worse, and it will still be studied and discussed - just like dinosaurs, the religion of the ancient Egyptians, and National Socialism are studied and discussed today - but it won't have any real signifigance to people.
