when did egypt begin believeing in god

Ancient Egypt began developing religious beliefs in predynastic times , at least by the 4th millennium BCE, and those beliefs became part of organized Egyptian religion by around 3000 BCE after political unification.

What that means

• Egyptians did not suddenly “start believing in God” at one exact moment.
• Their religion grew over time from local gods, burial customs, and ideas about the afterlife.
• By the Old Kingdom, religious belief was already deeply woven into society.

Simple timeline

• c. 4000 BCE : early depictions of gods and the afterlife appear.

• c. 3000 BCE : religion is clearly integrated into Egyptian society.

• later centuries : major texts and rituals develop, like the Pyramid Texts and Coffin Texts.

In one sentence

If you mean ancient Egypt , its belief in gods began very early, thousands of years before the common era, and evolved gradually rather than starting on a single date.
