Riddle Time #1: What am I?

I am formed by fire, flames from within
Then freezing temperatures, stiffen my stance
Assisting the apes, that dwell in wood and stone
Aroused from sleep, placed next to a pool
Lifted then lowered, into dark and deep
Lifted again, raised with rewards
Brought to my cave, to give up my gifts
This ritual repeated, again and again
Until the pool is empty
Return to rest, my job is done
Until the pool is full again
What am I?

Riddle Time #2: What Am I?

There is a limited amount of me
But I can make an unlimited amount of products
I tell you everything
But never speak a word
I am known across the world
And I have a few relatives
Yet whenever people see me
They only see my products
My very existence depends
On those who use and understand me
You might think I am a word or a language
But you only recognize them because of me
What am I?
