"Who am I?" Riddles

I am the third from a sparkle bright,
I thrive throughout the day and night.
Deep in the path of a cows white drink.
I've had thousands of millions of years to think.
But one of my creatures is killing me.
And so the question I ask to thee,
is who am I?

Until I entered Belgium to be handed my fate.

You throw me out when you want to use me and you take me in when you don't want to use me.
Who am I?

Who am I?

The more you have of me, the less you see.
Who am I?

All about, but cannot be seen,
Can be captured, cannot be held,
No throat, but can be heard.
Who am I?

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.
Who am I?

I follow the orders of only two.
I respect the work of only two.
I am in constant battles with many,
Though one surpassed them all.
With forces joined,
We created hell,
Until our mutual enemy fell.
Who am I?
