If so, the Lucifer would have to have destroyed the planet prior to the battle...otherwise there wouldn't be an almost completely intact pilot & Hercules left on the planet. The Lucys beams are powerful enough to level cities (based on that FS1 cbani), so it'd almost certainly incinerate any bodies.
Any craters could just as well be debris from the battle, in any case. I think the point of the cutscene was to show the pilot lost, doomed and stranded on a dead world - he died fighting for a ball of dust and rock.
Of course, we don't know that the Shivans are xenophobic. all we know, is that they have destroyed 2(?) worlds - Altair (IIRC...the Anicents planet and Vasuda), and the Capella star. All 3 cases could have potentially been 'touched' by the Ancients in some way - Altair as a colony, Vasuda as possibly a 'child' race which was assisted in developing starflight, and Capella potentially as a result of the Knossos network located several systems away.
