Why is a dark sky read as a beginning?
Because there is nothing to look at. The moon sits between us and the sun, unlit from our side, and the cycle restarts from something invisible. People sowed into ground that showed no result for weeks, and the sky matched the work. That is the whole borrowed image. A beginning is mostly invisible, it looks like nothing for a while, and the fact that you cannot see progress yet is not evidence that there is none.
