I am in the past never in the future. I don't exist but have existed. I saw what you saw and that is what I will ever see.
I am expelled from you orally with a sound
I speak without a mouth and hear without ears. I have no body but I come alive with wind. What am I?
What is made of wood, but can't be sawed?
