What does everyone have that increases, but never decreases?

What is it that,
after you take away the whole,
some still remains?

From the beginning of eternity
To the end of time and space
To the beginning of every end
And the end of every place.
What am I?

At night they come without being fetched,
and by day they are lost without being stolen.
What are they? 

What gets wetter and wetter the more it dries?

I know a word of letters three.
Add two more, and fewer there will be.
What word could this be?

Throw me off the highest building,
and I’ll not break.
But put me in the ocean, and I will.
What am I?

It’s true i bring serenity,
and hang around the stars,
but yet i live in misery,
you’ll find me behind bars.
With thieves and villains i consort,
in prison i’ll be found,
but i would never go to court,
unless there’s more than one.
Who am i? 

Though liquid to start,
don’t push me too far,
for then I will break,
and the damage may scar.
What am i?

I can sizzle like bacon,
i am made with an egg,
i have plenty of backbone, but lack a good leg,
i peel layers like onions, but still remain whole,
i can be long, like a flagpole, yet fit in a hole,
What am i?
