This got me thinking - If these spores are breathed-in, then that could play into the Pilot suit with it's elephantine, respirator-tube.
Whats also interesting is that now, it would seem that where the crew of the Covenant crashes is on some planet, where the Engineers tried to Engineer life, and perhaps, this time they used a slightly different variant from the Goo that made us. The result being this lush 'Paradise' where life begins, somewhat DIFFERENTLY.
The other possibility, based on some of the leaked set photos, is that Paradise was over-run with the Goo, in an attempt to 'Evolve' the Engineers and it wiped them out before spawning THIS STUFF.
Maybe their gods tried to evolve them?
This whole mythology just got even BIGGER than it did in PROMETHEUS. Anyone else seeing that?
