Answer:
I can be used to type and point you see. But don't forget, you can count on me. What am I?
I'm white, I'm round, but not always around. Sometimes you see me, sometimes you don't.
What has a big mouth, yet never speaks?
I saw a strange creature. Long, hard, and straight, thrusting into a round, dark opening. Preparing to discharge its load of lives. Puffing and squealing noises accompanied it, then a final screech as it slowed and stopped.
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 breath on this terrestrial ball.
I have two eyes in the front and a lot of eyes on my tail
