The More There Is The Less You See
The more there is the less you see. What is it?

Darkness. There more darkness there is, the less you can see.
I’m Not an Enjoyable Friend
I am something many people don’t enjoy having as a friend, including you. But I am called upon anytime someone is injured. I have 5 letters and when my last letter is put before my first letter, I become a country.
What am I?
Pains. No one enjoys being in pain, when you’re injured you have pain, and when you move the s to the front, it becomes Spain.
Serve Many But They Forget About Me
I serve many, confirmed by how healthy those I serve are. Yet after they’re successful they forget about me. It’s true, sometimes I hit them and they’re often bloody, but they don’t mind.
What am I?
A doctor (more specifically, an obstetrician) or a midwife. They deliver thousands of healthy babies but they are soon forgotten. Sometimes they smack the baby on the butt to clear the airway, and newborn babies can have blood on them from the placenta being pulled from the walls of the uterus or from an episiotomy.
Feared By Most But Experienced By All
I am a five-letter word and am feared by most but experienced by all. If you remove my first and last letters I bring life. If you add an ‘r’ between the third and fourth letters I am almost nothing and if you remove the first letter from this new word, I am your home.
What am I?
Death (eat, dearth, earth). No one can escape death, but many fear it. Removing the first and last letters leaves eat, and we must eat to stay alive. Adding the ‘r’ turns death into dearth, which is scarcity and removing the first letter of dearth leaves earth, where you live, assuming this riddle hasn’t reached extraterrestrials.
Full of Holes Yet Full of Water
I’m full of holes, yet I’m full of water. What am I?
A sponge.
Liquid Splashes But None Seeps Through
When liquid splashes me, none seeps through,
When I’m moved a lot, liquid I spew,
When I am hit, color I change,
And colors I come in, quite a range,
What I cover is quite complex,
Yet I am very easy to flex.
What am I?
Skin
An Eye In a Blue Face
An eye in a blue face
Saw an eye in a green face.
“That eye is like to this eye”
Said the first eye,
“But in low place,
Not in high place.”
A daisy in the grass. The big eye is the sun.
This is from J.R.R Tolkien’s The Hobbit.
