Those people say that humanity has only two ways of developing.
One stands for becoming a multi planet species while the second way is just for trying our best here on Earth as out predecessors did for ages.
And it is hard to argue with those statements. Scientists are working day and night to develop that futuristic technology for long and successful space travels.
As we are still here on our native planet,
we face more and more difficulties with wars, climate changes, epidemics, etc.
Those Mars colonies could save our species and help to save the whole Earth.
And both those ways are connected closely to the evolution of humans.
What will we become after years spent here on Earth and Mars?
What will humans evolve into while living on that distant planet with red sand, no atmosphere, and total isolation from the humanity? Let’s think about it.
