Heading to Earth

I'm the only one of my kind.
The only one you'll ever find.
Lonely existence,
The hell that this is,
A doomed race for all of time.

I've searched the universe for
Something that I could love more
Than being alone.
But everything's shown
Long ago I closed that door.

This is my goodbye to you.
A chance to say that you knew.
I'm heading to Earth.
That's all that I'm worth.
Nothing left for me to do.

When you find me on the ground,
Please try not to hang around.
Nothing more to see.
It's the end for me.
I'll not make another sound.
