To echo your point—the “from the dawn of existence, up to this moment” framing seems to me a fairly familiar way for amateurs to reach for gravitas, in wedding speeches in particular, and especially between partners both of a certain social milieu…

I wonder how much creativity matters for this type of work.

I’m reminded of iPhoto’s little chintzy auto-generated reminiscence movies. Nobody confuses those “Ken Burns Effect” auto-slideshows with, well, Ken Burns’ work—much less art or creativity—but I still find myself moved to see my memories all hookered up in that format sometimes.
