Plate Tectonics has been going on essentially from the when granite crusts formed from molten/semi molten surface material. This, by extension suggests the early presence of oceans and atmosphere which would have been blown away by the solar wind, etc. without the protection of the magnetic field. Plate tectonics are closely related to magnetic field generation.
I know this is kind of geek stuff but I find it fascinating.

Shouldn’t there have been a magnetic field for as long as there has been a spinning iron core? That would be pretty much as long as there has been an Earth.
