It’s my turn:

Where am I?
-I tried it for a few hours, there are granite chess tables all over the world,
the background image is blurred, if only these staircases were in focus,
maybe I would have found it, but I keep looking, I'm curious man... hehehe...
I was supposed to leave, but I decided to look for it and so far nothing,
difficulty level: very high this image/place...

Why not use a piece of paper?
Right, good too. And then, where would you keep this piece of paper
for a period longer than ten years,?
it cannot get wet or catch fire, moths cannot eat, also, rats eat,....
and if you keep it in your house in a place where nothing like this happens,
then, for various reasons, you need to leave your house and never come back and or,
If a disaster happens and your house catches fire after
a short circuit in the electrical wiring, would you have kept this piece of paper
somewhere else?, where would it be? In nature under a rock inside a container
that does not get wet or catch fire and not even insects or animals
would have access, but it was well kept, but being in nature and this place
you chose, over the years it became an environmental reserve?
And or was a construction made right on top of ?
where you kept your secret key written down on paper for more than ten years?
