Original Eggs on the Derelict - Elizabeth and the Drawings by David

One of the drawings by David shows an original 1979 chestburster. The same drawing reveals a female body as well, but it is a human one. We can see the phrase 'Female Human' in the drawing.

If I'm not mistaken, there was only one female human on Planet 4 when David proceeded with his experiments - Elizabeth Shaw.

We know that the Oram chestburster looked significantly different compared to the one in Alien 1979. Without doubt, Oram was attacked by a facehugger made by David.

I believe all of these facts lead us to the conclusion that Elizabeth was planted by an/the original facehugger taken out from an original egg created by the Engineers. If I know correctly, this egg made by the Engineers is mentioned in the Alien Covenant novelization by Foster.

I think it can be claimed that the eggs on the Derelict are original eggs made by the Engineers.

'Female Human [refers to top three illustrations]'
