Just a note that I don't think that the whole "Meaningless" theme of the song is sarcastic, but rather a sort of ironic articulation based on a materialist/naturalist (philosophy involving the lack of supernatural existence) perspective. It was meaningless, just like when fireflies fluoresce, just like everything. But just because there is no "meaning" to anything in the grand scheme of things does not mean we can't interpret it that way. At least, that's just my interpretation of this song- it's a bit personal, but also is about the way we think about certain words like "meaning" on different levels.
