Mephis: "angels collecting dust (or whichever inanimate materials are supposedly required) and making their own bodies to impregnate women.
good point I had not thought of that aspect, and how about the the body that Jesus is supposed to have materialized to convince Thomas. In these supposed cases, it was life, non-biological life, that manipulated the dust, the ground rock. If, when human - created life fires up, It would depend very much on the technical aspects to see how believers of various shades react.
