The impression I got, and it all happened really fast, is that these craft are artificial, they are manufactured in some way by an advanced civilisation, but that they are also given life in some manner. I can only speculate, but my guess would be, that perhaps biological life-forms who can no longer exist in a biological body, due to the vagaries of time, can transfer their consciousness and soul into a machine like this giving it life so to speak. Another possibility, is that a long time ago, this civilisation started merging with machines and in time essentially became entirely machine-like, but still possess the essence of a living being, which is a soul.
