This may work for phanerozoic bacteria, proterozoic metazoans and the early
Cambrian fauna, but how does it work for the entire order of successional
appearance? Is it your position that all of the forms of vertebrates, from fish to
mammals, were also created at the same time and just didn't manage to leave behind
a trace until hundreds of mlllions of years later? How can this be explained from
your perspective without multiple creation events?
