Correct me if I'm wrong, but I think this is how it goes...
1. Begin with mysterious canisters of BLACK GOO on Engineer "weapons silo" planet.
2. Black goo, when ingested by a human and spread through sexual intercourse, creates a FACEHUGGER in the female human. (In Prometheus, the facehugger would have likely burst from Shaw's womb if she didn't c-section it first.)
3. Facehugger does just that - attaches itself to a human/Engineer face, doesn't matter if it's male or female - and then somehow "impregnates" the host with a CHESTBURSTER.
4. Chestburster obviously bursts from the host's chest (though, in Covenant, we see one bursting through a victim's back), eventually grows into a XENOMORPH.
5. Queen Xenomorph lays EGGS with facehuggers inside... rinse and repeat.
The question is, does DAVID create the (first ever) facehugger by altering the black goo in some way (which he eventually gives to Shaw's boyfriend, who then has intercourse with Shaw) - or - was the black goo ALWAYS intended by he Engineers to create facehuggers through the same process, and had they created them before?
Also, where does the queen come from? Does David create her as well?
