Yom Rishon

Why start it on a Sunday of all days?
Supreme, he could have started on a Friday
and still be done on time with no delays,
the Universe completed, nice and tidy.
The Pentateuch would call it Yom Rishon,
and start the count, though off by a few billion,
list Satan among other hangers on,
and unaware we could have been reptilian,
put humans at the top of all Creation.
How special must we be, it took a week,
six working days to put us in our station,
omnipotence and all? Now that's unique!
Perfection thus achieved, He took a day,
and damn the consequences, come what may.
