It is difficult to go anywhere and not see signs of what was the dominate species. Everywhere you look abandoned structures liter the landscape. Their population had collapsed seemingly overnight about a century before we arrived. Did any survive?
Studying artifacts, we are piecing together their final days, but no living specimens found.
Conclusive evidence proves they are extinct. In the last century of their existence they drove tens of thousands of other species to extinction, they filled their seas with artificial materials and changed their climate. They could have stopped it. Good riddance.
