Riddle me, riddle me, rin-е-go, mother gave me some seeds to sow. The seeds were black, the ground was white. If you riddle me that, you'll escape my bite.
What are they?
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?
