Answer:
I cannot be felt seen or touched. Yet I can be found in everybody. My existence is always in debate. Yet I have my own style of music.
Curtail me thrice I am a youth; behead me once a snake; complete I'm often used in truth when certain steps you'd take.
lighter than feather and softer than silk yet the strongest man in the world cannot hold me for more than a few minutes.
I belong to everyone. Sometimes make you happy sometimes make you sad. I will never end until the day you do.
I am what bring things together. Without me everything you see would be a total mass or debris everywhere.
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
