You're asking an absurd question. You're disingenuously conflating intentional, human manufacture with natural processes that happen automatically, with no purpose or intention needed.I hate to get involved, but I will. Just based on that sentence alone, are you saying that the making of the atomic bomb is natural, unguided and automatic?
Water freezing or a tree growing from a seed do not require intentional direction or planning by any outside source. They are the automatic, and the mechanisms of action known. They are not comparable to manufacture.
