Which came first; life or death?

There couldn't be death without life, so life came first.

Death before LIFE was breathed into it, of course.

Life. A thing isn't "dead" unless it was once alive. 

Non-life then life then death. 

A single cell organism formed from Amino Acids which are the building blocks from all life forms on this planet....It's taken billions of years to create so many different forms of life and millions or billions of life forms lived and died before evolution created a creature with a workable thumb and a open mind to go with it....:)  

Life cannot die without being alive first.
