Personally I think this should do. Why not just delete all the old shit and let the Earth history be just a dramaturgic explanation of why things ended like they did?

There's nothing left anyway, except some transdimensional jews or whatever they think they are.

I'll make plans to have different infernal kingdoms take them in for repayment through labour (and more for those who aren't satisfied with that) and then we can just emulate the rest.
