The vast overwhelming majority of matter in the universe is inert.
The fact that we've hit upon a certain arrangement of matter which yields consciousness and the ability to manipulate the matter around us is something which seems worth preservation.
I contain the information for how to give life to inert matter. I've done it three times now, and I think it's worthwhile.
You thinking it is worthwhile is all that should matter, just as a farmer thinking it's worthwhile to build a wall that lasts. Both instances are us giving meaning to self actualisation of individual drives be it preservation or propagation of genetic information or building something that will outlast you.
