Although I don't believe it...the engineers could be the forerunner.
They nonchalantly float around experimenting, building and dismantiling, gathering knowledge. Now, a species like this has very little forethought...so maybe they accidentily engineer the flood? Now they can't control it, so they simply and calmly build a gigantic construct designed to destroy all life in the universe.
A most likely incorrect but admitedly viable theory...
