I am always wonder how would these civilizations would be today if they left to grow alone, without the European affection and love. Like we couldn't even have access to them until we have satellite internet, human rights, European committee, global journalism, things that could hold the 'explorers' from committing civilization crimes and for completely vanish exotic cultures.

What it would be like to have a conversation with a native american about their land and their forest, how far would Aztecs would reach, what relegion does the Rapa Nui people really had, and so many wonderful things we could get from people of Africa and all over the world.

Even then, their ground would be taken, their villages would be burned down and nobody would know. Is it possible to leave such a big continent to people without guns? Is it possible to leave them live the natural life they choose to live, without forcing them to settle in a house like our ancestors did 12.000 year before? And because of that my back hurts, my body is stiff, I have anxiety for virtual things and my connection with the nature is broken.

But no more cultures left to modernize in Earth, let's find another planet to help.
