This assumption makes sense given the limited modern scientific view of the world, but it falls down pretty hard when you consider how incomplete our understanding of the universe still is.
The piece of knowledge which is still missing, and which you should direct your search if you feel the way you outlined in your post is, what's consciousness? What're the mechanisms by which it functions? We might be biological machines with a single, hardcoded directive in one sense, but it's very inside the realm of possibility we possess the potential to escape that.
