I always subscribed to the theory that the Engineers represented a physical image of Heaven’s fallen angels (demons). These once supreme beings lacked the ability to reproduce and were envious of Humanity. Humanity being God’s prized creation. The Engineers didn’t engineer Humanity but more so wanted to corrupt their DNA and thus, taint the fruits of God’s garden so to speak.
I always saw the Engineer’s plan to eradicate Mankind with the Black Goo as a metaphorical display of the Biblical rapture. The Black Goo doesn’t outright KILL the host - it transforms it into an abomination of sorts. Much like demons corrupt a soul and distort it and turn it into something ungodly.
So no, I don’t think they see human females and their ability to reproduce as sacred but more so a trait they’re envious of and they have a natural disdain for Humanity because they themselves are outcasts and we are the “saved” beings who still have access to an eternal life free of pain upon our death.
