Is it Adam's and Eve's fault that we have to suffer?

Many say that we are inbred from Adam and Eve's children getting married to one another; but look at Adam and Eve themselves. Eve was made directly from Adam, so that means Adam married and had children with his very own clone. The exact same DNA! This has caused great harm among people such as why our teeth can not repair themselves, and why we do not live to be 900, and why a simple calculator is faster and smater than we are, and much, much more!
