Deal with the inventor

Hey gang,
Now I have heard of how aliens created human biengs, But that makes me ask...If it's true that we are just an experiment then how in the world would our govn't officials be able to make deals with them? If they are our creators then they certainly don't need to make any deals with us. Don't they kind of own us? They can do whatever they want without any consent from us. That is, if they created us. Watchall think?
