The dinosauric age came to an abrupt halt.  They began to die out.  I just bought a child's book on the "Wonderful world of Dinosaurs" by Disney that gives a great overview of the different kinds, categories, and a general time line of the dinosaurs.

There is also a section on a giant asteroid impact that says that dust and ash shot into the atmosphere worldwide and blocked sunlight.  The impact would have caused earthquakes, tsunamis and acid rain.  Scientists today think that is what happened.

I'm through with all that.  Simply wanted you to know about the "blocked sunlight", because that brings us to the second word I told you that I was interested in.  "Let."

Genesis 1:2  "And the earth was without form, and void; and darkness (blocked sunlight) was on the face of the deep.  And the Spirit of God moved upon the face of the waters."
Genesis 1:3 "And God said, Let..."

I take this word to be very different from "create".  You recall I said that 'create' meant to make something where nothing had been before.  Something entirely new.  But "let", put simply, means to allow something to happen.  For instance, "I'm going to stop at the corner and let you out of the car."   Nothing is created.  Someone is in control of the car.  They stop, open the door, and you get out.  They "let" you out.

Genesis 1:3  "And God said, let there be light: and there was light."   He didn't have to create it, he did that back in Genesis 1:1  The only thing God had to do was restore it.  Let sunlight pierce the darkness.
