Well, it's official now.
Scientists have determined that an asteroid did in fact kill the dinosaurs.
Read about it here.
The link's broken.
Without having looked at it, I got to say I'm a bit skeptical. My Christian worldview aside, even if we know that they died 65 million years ago, I've very skeptical that somebody can say for a fact that an asteroid killed them. Heck, there could have been a worldwide reptile virus that killed off the dinosaurs, and an asteroid just happened to hit the planet around the same time.
Just my quick two cents anyways.
