Is the following sentence true or false the Precambrian represents a much longer part of history then the Phanerozoic?

True. The Precambrian encompasses a vast period of Earth's history, spanning from the formation of the Earth about 4.6 billion years ago to approximately 541 million years ago, accounting for roughly 88% of Earth's geological time. In contrast, the Phanerozoic Eon, which follows the Precambrian, covers the last 541 million years and is characterized by the emergence of abundant fossil evidence and complex life forms. Therefore, the Precambrian indeed represents a much longer part of Earth's history than the Phanerozoic.
