It's been a while since we had dozens of topics about this, seems like two in one week is appropriate.

No, George Bush did. Ask Odumbo, he inherited it.

No, actually I believe it was due to an early Cro-Magnon man named Al-a-Goric.

It would make more sense for us to develop the technology to detect and deflect comets and asteroids than to go back to the Moon or Mars.

Ruminant grazers survived the extinction, non-ruminants were wiped out.

You need a theory to accomodate this.

One little problem..... The end of the American megafauna also involved whatever created the gigantic muck deposits in the North and it’s not even obvious to me that a worldwide flood could do that, much less any sort of interaction with a comet.

Silly comet theory. It’s CAVEMAN’S FAULT. Those damn SUV’S they drove caused global warming.

Gigantic muck deposits? I live maybe twenty miles from the muck farms, which are flat, former lakebeds, which have of course long been empty of the lake waters.

I meant it as a plural "you" for apocalyptic scientists.

Physicists that come up with this stuff really need to hang around animals more.

First things first.

Where was Ted Kennedy when this happened and can he prove his wherabouts?

It seems pretty likely that’s what happened. And during an ice age, so that explains the lack of crater. There’s a whole layer of nanodiamonds right around that time period.
