About 540 million years ago.
The Precambrian Era began in the time period 4600 and ended in 570.
Yes it was
It began 4.6 billion years ago and ended 544 million years ago.
During the Precambrian eon, which spans from the formation of Earth about 4.6 billion years ago to around 540 million years ago, life was primarily simple and unicellular. The earliest organisms were prokaryotic, such as bacteria and archaea, and later, simple eukaryotic cells emerged. Multicellular life began to develop towards the end of this eon, with the appearance of algae and soft-bodied organisms. Overall, the Precambrian eon was marked by significant evolutionary developments, setting the stage for more complex life forms in the subsequent Paleozoic era.
There is some debate among experts, but it is generally accepted that the Precambrian lasted from 3.9 to 4 billion years. This time period is made up of three eras which are the Paleoproterozoic, the Mesoproterozoic, and the Neoproterozoic era.

The two subdivisions of the Precambrian Era are the Hadean and the Archean Eons.

Yes, the Precambrian era is the earliest part of Earth's history, spanning from about 4.6 billion years ago to 541 million years ago. It is followed by the Paleozoic era.

The Precambrian Era ended around 541 million years ago with the Cambrian Explosion, a period of rapid diversification of life forms. This marked the transition to the Phanerozoic Eon, characterized by the emergence of complex multicellular organisms.
