There are three parts:
The first part is about the beginning of the earth, how the words of GOD can be proved by scientific facts.
The second part is about the failure of man. The earth had been defiled. Man had been defiled. Then man lost eternity. Then Christ came to redeem man.
The third part is about the cleansing of the earth and the plan for man to have eternal life again and start a new beginning.
They are factual and fun. Enjoy them.
