The lyrics describe a time before the earth was round when things were infinite and contradictory, where love and war coexisted peacefully. However, with the discovery of the earth being round, everything changed and contradictions became mysteries, love became complicated, and the sky itself was unsure of how to react.

Meaning of "Before The Earth Was Round" by OK Go

These lyrics seem to reflect on the innocence and simplicity of a time before mankind's understanding of the world expanded. In this pre-round earth era, there was a sense of boundlessness and acceptance of contradictions, representing a more harmonious and accepting society. However, the discovery that the earth was round symbolizes a turning point where knowledge and understanding brought about a shift in perspective. The chaos and complexities that ensued portray a loss of innocence and a departure from a simpler time. The uncertainty of the sky at the end could signify a loss of stability and direction as beliefs and truths were questioned and reshaped. Overall, the lyrics may be interpreted as a commentary on how knowledge can alter perceptions, relationships, and the world itself.
