Dating back to the precambrian era

Erosion and plate tectonics has probably destroyed all of the solid rocks that were older than 3.8 billion years.The advent of a rock record roughly marks the beginning of the Archean eon.Once solid rock formed on the Earth, its geological history began.

The geological eons in Precambrian - Hadean was the burning inferno right after Earth's creation.

The spacecraft was about 10,500 kilometers (6,500 miles) from the asteroid.

The sun formed within such a cloud of gas and dust, shrinking in on itself by gravitational compaction until it began to undergo nuclear fusion and give off light and heat.

Hadean time (4.6 to 4 billion years ago)* is not a geological period as such.

No rocks on the Earth are this old, except for meteorites.
