Easy: Carl Sagan, Richard Feynman, Einstein, Rudyard Kipling, Richard Dawkins, J.R.R Tolkein.
I would be a man among gods, During the day we would walk the island and admire the fish from afar, Dawkins would teach us about the plant life and ecology of the world that surrounds us. Rudyard and Tolkien would write and speak eloquently of the beauty that encompassed us in its wake.
During the night we would lay in the sands with the surf crashing by our feet, We would stare at the stars and feel insignificant. Sagan, Feynman and Einstein would admire the cosmos and teach us of the wonders unreachable. The sky would be so clear that the arm of the milky way would arch over us like a canopy to the heavens, We would stare into the infinity and it would stare back into us. We sleep and we would dream, Not dream of a better world or a brighter future. But dream of tomorrow, Another day to try and understand it all and admire all the wonders of the universe.
People ask me what i want to do when i'm older, I always say "Study physics".
"Like sheldon cooper"
"No, Like a curious man"
So to answer the question, I would take 6 people to share wonder with. To ask questions with.
Because after all thats the most important thing in life.
