Riddle of the Day

[Gizmokid2005]

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?

ANSWER (I'll give you this one TL): Tomorrow.

NEXT RIDDLE:

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I'm double, I'm single,
I'm black, blue, and gray,
I'm read from both ends,
And the same either way.
What am I?
