Could be from any sacred scripture that you want.
Remember...it's just a theory...
OK...here goes...
Imagine God is ALL.
Everything that exists...exists inside of God (Heaven, hell, planets, stars, ants, galaxies, you and I).
God would be unable to look in a mirror and see Himself. The mirror would have to be outside of God to cast a reflection back at Him (and nothing exists outside of God). It would be like having a mirror inside your body...it would do you no good.
Now God asks Himself (like we all do)...why do I exist? What is My purpose? (God created man in His own image...we all ask that question).
Since nothing exists outside of God...God must look inwards to find an answer.
So God gets an idea. He could create "man". A being with FREE WILL. A being who doesn't know God, but will come to know God. Now if God sees thru the eyes of man and hears thru his ears and feels his feelings...God will get to know & understand Himself.
That would explain why we are so Important to God. Why He would create the earth twice...just for us to live on.
We are Gods attempt to understand Himself and His purpose.
Just a theory...But barry mannilow sang of the same idea.
My home lies deep within you...and I've got my own place in your soul...
Now when I look out thru your eyes...I'm young again, even though I'm very old
