Lyric discussion by Henley 

Cover art for Indifferent Suns lyrics by Dark Tranquillity

I don't know, but the whole chorus seems, to me anyways, to be saying that we're not the only intelligent life. "All along we keep staring at the sun. closing our minds, saying we are the ones." to me, that's just saying that sure, maybe the sun revolves around us, but as the song is titled, the sun is indifferent. that's just my take on it..
