Meaning(a poem) by me

In the vastness of space, with stars so bright,
Humans stand small, in the shadows of light.
With oceans and mountains, and forests so grand,
We're mere specks in the universe, just a grain of sand.

We build towering cities, and reach for the sky,
But when viewed from above, we are but a tiny fly.
Our problems and worries, seem so great and so vast,
But in the grand scheme, they simply don't last.

We think we're so mighty, with power and might,
But in the vastness of space, we are simply in sight.
For the universe stretches on, and will do so for all,
Long after we're gone, our legacy will fall.

So let us remember, how small we truly are,
In the grand scheme of things, just a speck like a star.
For we are but a moment, in time's endless flow,
So let us make the most, of this life that we know.
