Why do you need it to be slave labor so badly, despite the findings of archaeology?<quoted text>
Like the Egyptians put up a bid?
Then hired a contractor with the lowest bid?
Well the contractor so happened to be Abraham & Sons Inc.
No one could out bid them because they supplied free labor.
The truth is it was forced labor. Slave labor.
I see your problem here as a general problem of your religion - it denies science. You deny biological science, history and now archaeology.
What you're doing is precisely what the Exodus story in the OT does: creating a mythological story to give you a religious identity.
