From Paradise lost to paradise regained.
Pg 10 para 5
After a very long time the earth began to cool. And as it slowly cooled it changed from a ball of fiery gasses to a ball of hot boiling liquid. Very slowly a crust formed over this liquid, which hardened as time passed. We could compare the crust to the hard scab that forms over a cut in your flesh.
BTW this was not a children,s book.
