Everybody has a story

Universe is filled with realistic "life has reason to live" people. Everybody has a story, a motto and an experience to dole out with.
Each species feel them in their own way. They learn from each step and modify the next. Thats how it is.!

What if there's no thoughtful people, no sophisticated person to fool around with other being's life, what if all were same rationally and think same logically, would have been there an evolution ?
The earth would have been persistent, endless journey towards nothing but leading our life into indolent setup.
