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.
Born in the ocean and white as snow. When I fall back to water I disappear without a trace.
I come without being fetched at night hides away as soon as daylight strikes. Although I may look small I am much mightier than what you can imagine.
I am partially baked. I am not completely lit. I am a portion of the moon. I am lesser than full wit. I am a divider of the hour. I am not a total lie. I am a sibling through one parent.
I am quick when Iām thin. I am slow when Iām fat. Wind is my worst nightmare.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
