Grow in trees, eat living things
But have no teeth and
Give birth to something that looks nothing like me.
What am I?
I am what goes up but never comes down. I am needed but hated. I am useful in more than one way. I somewhat hold the future. What am I?
I'm not dead,
i'm not alive,
i'm not underground,
i'm high up in the sky,
people speak of me but never saw me.
Who am i?
