I don't get why we know very little about the planet's first 600 million years. What is the reason?


No rocks are known for the first 600 million years of geologic time. Although there are rocks beginning at 4.0 billion years, these rocks are difficult to decipher because they have been metamorphosed and complexly deformed, they are buried beneath younger rocks, and they contain few fossils useful for determining relative ages.

    That's even  before there was any life at all on Earth.

    Very primordial with dust, rocks, gas and lots of volcanoes.

    The Earth is 4.6 billion years old and they were there first 0.6 billion years..


    This is what Wiki says about that era ( The Hadean Era ).

    And your link says there are no samples before 4 Billion years ago. That is wrong. There are Zircon crystals in Western Australia which are 4.35 Billion years old.

    The amount known is relative to the amount knowable through discovery.

    Cos the history book is really thick and the print is very tiny.

    Thinking is so important.
