MemberOvomorphFeb-22-2018 3:46 AM@Indy_John I have a theory on answering your question in question to the line David makes.........
From the start of the movie we know that Weyland, Dr. Shaw, Dr. Holloway, the rest of the Scientists have their own personal goals/agendas they each want to achieve. We find out they have personal emotions to relate to, personal and different things that are meaningful to each character differently and different from the rest. Aside from their duties/job that they have been hired and employed to fulfill by the same company:
Weyland wants more life
Holloway and Shaw want to find their Creators
Vickers wants her dads (Weylands) company? Wants to feel loved by her father
Millburn wants to make friends (tries making friends with Feifield. Tries treating a face hugger like a kitty cat..............)
Fifield wants money
Janek wants to sleep with Ms. Vickers
The Engineers want to escape and head to earth
You get the idea here..... All these beings want something
If Weylands, Shaws, the Engineers, Holloways plans are successful then all these characters will, respectively, have something.
I don't mention David because his intentions are always foggy. I exempted him because he is an android as well. Not human. With David, it's somewhat difficult to pinpoint what he really wants. (I think it becomes a bit more clear of his intentions and goals in Alien: Covenant). I must mentioning his androidal existence because I believe it is crucial for understand further on why he uses this line and refers back to it later. Androids are without feeling... "needs, wants" no emotions nor feels pain. So, upon their arrival of the planet LV-223, the scientists read aloud their data of the planet.. I'm paraphrasing here but they say, "no radio, no heat, no nothing, nobody home." Right after this, David says his infamous line....
"There is nothing in the desert, and no man needs nothing."
David might be assuming, but, this place they're just arrived at.... is a desert.. and there ain't nothin' in a desert, cept sand o' course. (We later find out that after Weylands death, there is "something" of value in this "desert".. but of value to who I wonder? Could you guess?
(Keep in mind Peter Weyland is still in Cryosleep, so technically, he has also arrived on the planet). If we fast forward to the end of the movie when the Engineer runs off and tries to escape the planet, when Davids head gets ripped off, and when Weyland is laying on the ground about to die Weyland says, "There's nothing." David replies, "I know.. Mr. Weyland, have a safe journey". Basically bidding his father/Creator, Weyland, farewell who is leaving the desert... where there's nothing, and where he won't need anything else.
I see it like this: If you have one penny in your left hand and one penny in right hand you do not have three pennies. David give us a way more introspective, thought provoking, and a semi-backwards way of looking at it. If nothing is in front of you, nothing is there. If you go looking for water and green trees in an ocean of sand, you will find only dust.
Everyone onboard The Prometheus went looking for something in a desert, yet found nothing. If there is nobody to go looking, nothing is found.
David, a man of nothing. A soulless being went looking for nothing, and found everything. (Alien: Covenant)
Hope my thoughts on this subject gives you a twist on your thinking :)
