Wasn't that his cigar that he put in his mouth?
Also, I'm still not convinced this planet is the Engineer homeworld. It just makes more sense to me that it's a human-like race created by the Engineers, who worship their creators. When David turns up in the juggernaut and they amass in the square, I don't think it's because it's just one of their ships returning -- I think it's because this race, who revere their creators so much, are expecting a visit from their "gods".
I mean, I'm willing to be proven wrong. It'll be tremendously disappointing if so because yeah, it's wasted potential. But what in the film implies it's specifically their home world? I went to a midnight screening so might have missed something due to tiredness.
In the prologue David says: "We were able to activate their ship, and set course for their homeworld". That's pretty clear I think.
