Fastest traveller ever known, and never do I slumber. Ere you move I'm long since flown, A letter bears my number. But for all my matchless speed, The ancient and immobile tree, Responding to a primal need, Traps and trains my energy. What am I?
Until I am measured I am not known, Yet how you miss me When I have flown.
Who am I ?
I never was , I always to be . no one ever saw me n nor ever will . And yet I'm the confidence of all . To live and to breath on this terrestrial ball .
who am i ?
Guess me: Never ahead, ever behind, Yet flying swiftly past; For a child I last forever, For adults I'm gone too fast. What am I ?
