I never was, am always to be,
No one ever saw me, nor ever will,
And yet I am the confidence of all,
To live and breathe on this terrestrial ball.
What am I?
An arm points north, east, south, then west.
Ever in circles, never pausing to rest.
It passes its brother twenty three times,
As the sun passes by and the moon starts to climb.
What is it?
I say everything I hear to others around. I'm not an animal, nor part of the human race. I will, immediately, repeat after you; But only if my tail is in place. What am I?
