Sure we are created by God and are a part of God, but slavery has always been a major issue on earth with humans.We are not slaves. We are a part of God, and created by God.
Do you have a social security # ?
Your name is printed in all capital letters on your gov't documents ?
Then you are a slave.
Just like a soldier is a slave.
They cannot do as they like and their lives are not their own.
There are different degrees of slavery to be sure.
But whether your master is kindly, or beats you, is not the issue.
As for the story of man being made to be slaves of a technologically advanced species who came to earth eons ago....who knows.
I don't know if it is true or not.
Just another flower from the compost heap.
But it is just as plausible as man evolving by accident from sea slime and it is just as plausible as all the other myths.
Every last single idea of the origins of man are all speculation.
Nobody really knows.
But many say they do.
Tis just wishful thinking on their part.
