Rock Formation Built in Millions of Years, Lost in Seconds?

To the surprise of tourists, one of Australia’s seacoast rock formations called the “Twelve Apostles” collapsed into a pile of rubble before their eyes, reported CNN, ABC and other news sources.  The fall of the 150-foot high sedimentary formation was caught in before-and-after snapshots by a teenager.  Even though standard geology claims the rocks began to form 20 million years ago (see the BBC News story), the remains will probably be washed away by the waves within weeks.  Answers in Genesis took this event, and others like it, as evidence that such formations could not be nearly as old as claimed.

Let the evidence speak for itself.  Anyone infer millions of years with this kind of eyewitness testimony?
    Here is a candidate for Stupid Evolution Quote of the Week from a tourist, reported by News.com.au: “It’s pretty unbelievable; it’s history in the making today… It won’t be the same sort of photo any more, but it is evolution.”  Darwinism wouldn’t generate much of an edifice with this kind of process.  If the tourist meant that Darwinism itself is crumbling in a similarly rapid manner, well, then the remark would be rather astute.
