bible verse

meaning

Both phrases refer to a period in the distant past where a specific time could not be traced anymore.

origin and application

The time of Adam’s creation has always been a subject of interest to archaeologists and historians. The creation of Adam and Eve was calculated to have taken place six to eight thousand years ago, but some scientific data shows that the creation of Earth occurred much earlier – billions of years back. A school of thought emerges with the idea that the Earth was created millions of years before the birth of Adam so as to prepare for sufficient nutrients on the ground as food.

example
