Any thoughts as why the engineers all look the same and that there are no female

@ limitlessfrog - incorrect... According to religious texts the first Man and Woman (Adam and Lilith) were created at the same time, through the same process and equal to one another but they didn't get along and the first woman left. Then after a period of time alone Adam asked God for another female companion that would be submissive to him, so God created the second woman, Eve.
