There was no life yet. The Earth was still in the form of a hot glowing ball rotating on its axis. Its duration lasted approximately 2,500 million years ago.
The archaic period is the time of the beginning of the Earth. One of the relics of the archaekum period is the kraton rock or continental shield.
The age of these rocks is estimated at 3.8 billion years. This continental shield can be found in several areas, such as the United States, Canada, Venezuela and India.
