and may have increased the earth's oxygen levels to a degree that made the development of multicellular life possible... And here all this time I've been told that photosynthesis was the cause of the oxygen.

On a cellular basis, plants are more complicated than animals, so one possibility that has presented itself (from the materialist/reductionist perspective) is that unicellular animals appeared first, and then plants came along sometime later. That was difficult for the just-so school, who figured that plants woudl have to arise first. Extremophile bacteria of some sort are the leading candidates for the first Earthly life, but having a nice healthy catastrophe come along means having something to saddle on right away, y'know, for people who think that everything must have some connection with gradualism. :')

Was this impact (rocks) from which King Tut's jewelery was made?

You do know that 42.7% of all statistics are made up, don't you?

yes, what could be more sensible than gradualism?

"...structure in Yucatan which led to the extinction of the dinosaurs..."
Except if you accept the argument of Chatergee (sp?) in India who believes that the Shiva crater was also formed about the same time, 65 million years ago, and as a much larger structure, 400 by 600 kilometers, probably was a much more significant factor in the demise of the dinosaurs. As his beliefs are being questioned by others, does anyone have any late info on this argument?

I think the term "gradualism" is usually called "uniformitarianism" so they can rope in geologic change as well.
Of course uniformitarianism is totally wrong.
