Asteroid

The beginning of rocks. The Amino Acids. The shooting stars. The meteor showers.

I'm not sure if words are enough to paint this amazing creation the same as how it is painted in reality.

I remember the rocky surface of the moon. I reminisce the movies, and news of craters on Earth.

Sentimental? Maybe Elemental.

My point is that it starts with letter A, and that explains everything here.
