Davids Lab isnt Davids at all

I propose that "Davids lab" that we see in the trailer, the one with the pictures, specimens, and the dead body with a hole in its chest, might not actually belong to david.

David is an android, so I see no need for him to paint / print large pictures of facehuggers and xenos, since he has digital memory, and the specimens all laid out neatly and labeled on the table seem like the style of a living organism, not David.  Why would he display and label things anyway? For his own good? Why the labels? He doesn't need to remember what each object is, hes an android.

Perhaps the room belonged to whatever lived there before, be it human or engineer, and they were the ones experimenting on facehuggers and the black goo, which got out of hand, leading to their destruction, and the black burnt bodies we also see in the trailer.

Just my thoughts on the matter.
