Query: Who's afraid of the dark?

The concept of a world which has never been in shadow, never looked to the stars and contemplated are we alone? is amazing at the very least. The story as a civilisation hopes to prepare for something they just simply cannot comprehend is believeable. The event occurs only once every 2 thousand years, so most people are blissfully unaware yet the ruins of previous civilisations hint at a regular catastrophic event where people revert back to barbariasm. The main question that troubled me was with all OUR previous grand civilisations is there something we should be aware of.
