Answer 3

At the hadean because collisions between large planets released a lot of heat, the Earth and other planets would have been molten at the beginning of their histories. That time was not part of the geologic history because the earth was way too hot for animals and bacteria to even survive. There wasn't rock that was that old except for meteorites.
