Why haven't paleontologists found any rock from the earliest years of Earth's existence?

Answer 1

All rocks were molten in that period of time.

**Possible improvement

All rocks from before the Cambrian Period have been melted and recrystallised, as far as is known. (Though I don't fancy testing the age of every single rock on earth - do you) In the same way there are no Pre-Cambrian fossils. We have not tested every single fragment on earth, so all evidence is destroyed.

Answer 2

The lack of rock from Earth's earliest years is mainly due to the intense geological activity over billions of years, such as tectonic plate movements, volcanic activity, and erosion, which have destroyed or altered most of the original rocks. Additionally, the Earth's surface has been extensively reshaped through processes like weathering and sedimentation, further obscuring remnants from its early formation.

Answer 3

All rocks were molten in that time period.

Answer 4

The earth was too hot
