So...ID doesn't care. It is willing to work with long timeframes.
I on the other hand do care. We've seen the glaciers redated to much earlier dates, we've seen the European neanderthals redated to within Biblical timeframes, we've seen theories about how long it takes to petrify something reduced, how long it takes to build up sediment reduced, how long it takes to make a Canyon reduced. As science advances, it will probably eventually correct itself.
"The “Cambrian explosion” refers to the geologically sudden appearance of many new animal body plans about 530 million years ago. At this time, at least nineteen, and perhaps as many as thirty-five phyla of forty total (Meyer et al. 2003), made their first appearance on earth within a narrow five- to ten-million-year window of geologic time (Bowring et al. 1993, 1998a:1, 1998b:40; Kerr 1993;"
No. You have seen creationist hypostheses, you have seen no theories.
