SOULS!!!

WHY WERE THEY CREATED??

I was told that God is the creator. So tell me..........
We live our lives choosing our paths at every fork: good or bad.
If good, we r said to reborn as higher forms till we attain moksha and become one with God.
If bad, we r reborn as lower forms till we become one with the Devil.
And we keep circling around till our choices are consistant.

The driving forse of our existance is called the SOUL- And that i believe.

It is said that souls have to go through birth and rebirth to find one's place with god or the devil.

All this would have made sense if souls already existed or were created by a third person.
But! God Creates All!!
God created souls which then have to find their true destination.

So why create souls at all???
What is the purpose of existance???
Are we just the pawns in God's game of life???
