Interesting question. I would definitely want someone who stands for peace, love and compassion in a central position of leadership here. I want our new world to be different than the one we have now, a place that prioritizes the welfare of it's inhabitants. I am going to appoint the late Bishop Desmond Tutu. Because of how he fought the global aids crisis I am confident he'd build a society that provided care to it's sick. I also expect a world where people of all backgrounds have equal civil rights because of how he stood up against apartheid in South Africa and the apartheid against the Palestinians, and supported women's rights as well LGBT+ community. He even advocated for animal welfare- that's important for me because I want to treat other creatures that we might find living in this new land with respect.
I have the guy who is going to be the conscious, now I need someone who can fight, just in case we're invaded. I don't want to chose a famous conqueror though, because I don't mean for my people to become invaders themselves or to try to build an empire, I just want someone who can organize the people in a time of emergency. I'm thinking either Spartacus or Che Guevara.
I have the courage and the heart, the third is going to be the brain. I choose Leonardo Da Vinci. He will be our engineer, if he explored the use of solar power, designed parachutes, revolving bridges, aircrafts, cars, deep-sea diving equipment, calculators and robots back in the Rennaisance, then just think of what he could build in this day and age!
So this my ruling council of three elders.
