What is this reality? As comprehensively as you can, in about 40 words or less.

“Hello, babies. Welcome to Earth. It's hot in the summer and cold in the winter. It's round and wet and crowded. At the outside, babies, you've got about a hundred years here. There's only one rule that I know of, babies—God damn it, you've got to be kind.”
― Kurt Vonnegut, God Bless You, Mr. Rosewater
- And it's so damn good to be here. In the cold, in the hot, in the empty. It's a good suffering
  
  Everything was beautiful and nothing hurt.

We are made of star stuff, just like rocks, but we are curious and can learn. We are a way for the universe to know itself. We process matter with our industry and our digestive systems.
Just like a spider knows how to spin a web without being taught, we carry instinctual knowledge, but we also carry cultural knowledge from our life experiences. We are like organic computers. Emotions are a different way to solve problems when our logic fails.

All matter is merely energy condensed to a slow vibration, that we are all one consciousness experiencing itself subjectively, there is no such thing as death, life is only a dream, and we are the imagination of ourselves.

Bunch of tree dwelling apes who developed language to tell good vs leoparded trees after most of the trees died; went too far and are going extinct by finding a great filter they can't invent out of.

Is this the real life? Is this just fantasy? Caught in a landslide, no escape from reality Open your eyes, look up to the skies and see.....

Chaos+ entropy+ lots of space and time. Everything is in motion of some kind. Nothing will ever be like it once was. Enjoy yourself when you can. Love your self and respect life. Be kind to those that have less than you. Look at creation and wonder.

A mere coincidence. The world just randomly happened to be like this. And you just randomly happened to be a human

Nothing means anything, just find your happiness where you can and be good to each other.

Reality is the matter we act upon, using energy.
I believe it is your responsibility to properly use energy you control. Moreover, you will always have excess energy that you need to dispose of somehow (living things need to collect more energy than is absolutely required, or they risk death).
Note that a collection of energy that is expended improperly is called a "bomb".

A reaction to the creator's poetry. Like contriving words for a tune. Except instead of words it's sights, sounds, money, gravity, thoughts, people, etc.
