Why Reason?

Reason, Why reason? What sparked the first reasoning, And why did it evolve into reason? We seek reasons, Death, a reason, Life, its own reason, Reason, reason, reason. They say everything has a reason, But why did it become the answer? Success and failure, each with a reason, Is there a reason behind the reason? I'm still puzzled, Though it seems logical, It's quite a conundrum. I may attempt to comprehend, I may offer examples to recommend, Yet my question lingers, Why reason?
