@Procrustes,
Many "metaphysical" questions seem to reflect the limitations of our language. Pyko's question regarding the origin of space suggests that it is some kind of "thing" that comes from "somewhere". Procrustes' reference to the child's universal query, "But why", as an expression of the "psychology of questions", the "causes" of questions reflecting assumptions about the ontology of "things", how every "something" must come from "somewhere" is more about linguistics than Science.
Fundamentally, I think we should bracket or ignore all terms like origin, absolute, causation, things, beings, and space, time and Truth, etc. etc. when we try to relate in some immediate way to the Totality of Reality. Our posture must be one of Reverential Ignorance (or agnosticism). A Korean zen master advises his students to meditate with the notion of "Don't know" on each out-breath. I prefer that to filling my head with all the artificial constructs of our cultural-metaphysical presumptions--the ingredients of "confusing webs" more than liberating information.
