Watch a documentary called "Into eternity" and Google " Onkalo".
This facility must last 100 thousand years...Nothing in the history of humankind last a tenth of this time.
100 thousand years from now... even if we left some type of warning saying: "leave this place alone, walk away"...definitely will going to have a new civilization that probably will not speak any of of the languages we speak today.
It will be something like open a pyramid, they will think that there's some kind of treasure inside.
And if someone " in the future" found this place, what would they think about us?
