The World

 I am so large, and no one ever gets my exact lenghth

Only because I am too large to be measured

The extent of my extensibility is unpredictable

Human can try but they can never get my actual lenghth

scientists can form an hypthesis about me, but they can never prove it

My lenghth is an unsolved riddle that can never be solved

Humans can never find my secret because they dwell in me

I am the only reason they exist in the first place and at the end,

I would be the only reason they would exist no more

But for now, I bear their weight,

I share their thoughts,

I share their feelings,

I share their love and I also share their sorrow.

I am capable of taking care of humans, because its a vow I made ,

and I promise to always be there for them as long as they never discover my secret

and my secret is my lenghth, and my lenght is an unsolvable riddle.
