Pale blue dot: a vision of the human future in space
By Carl Sagan
In this book he described how human started his struggle by hunting animal for food to exploring the world from known seas to unknown ocean and exploring the space today and what will be human future.
In his word
” Pale Blue Dot is about a new recognition, still slowly overtaking us, of our coordinates, our place in the universe and how, even if the call of the open road is muted in our time, a central element of the human future lies far beyond the earth.”
