I know it's flash, but the ending wasn't complete. Maybe I'm dense but, in my opinion it didn't answer the question of why the aliens were there.
The aliens were there to activate human's unused DNA (ouch, it pains me just to type that), which will make humans share in the universal love. I thought that was pretty clear.
Whether this is a good or bad thing, whether this is a matter of uplifting the human race or a subtle form of conquest is up to the listener, but that's a matter of being open to interpretation, not a matter of incompleteness, at least in my impression.
Not that that salvages the basic premise of the story, though.
