What amount of energy was required to create the earth in the first place? Arent we ignoring God in the energy statement?
Do the orbits have to be that predicable? Are they not capable of being influenced after they left the earth originally and we only now see the stabilised orbits?
I dont think steady state science can be assigned here…the biblical deacription essentially calls the flood a catastrophically desctructive global event. So when you say vaporised…isnt the limiting factor in a steam explosion exactly that…the amount of vapour…so the explosion is self limiting in that once the vapour is gone it stops…wouldnt the fact its also water driven also prevent vaporisation of the earth. Water is a strange substance in its characteristics.
Let me put it another way…Adolf Hitler had his military build a gun that fired a 4m long shell about 40km. we dont need to scale that same illustration up much to have a shell leave the earths armosphere…especially given the generating device is the earth and it not a pissy little 100 foot long gun we are talking about.
