You bury a plant.
I believe the answer is a plant.
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?
I have many feathers to help me fly. I have a body and head, but I'm not alive. It is your strength which determines how far I go. You can hold me in your hand, but I'm never thrown.
What am I?
