ROCK ON (AND ON)

A recent study on the meteorite that plunged into a Canadian lake in 2000 says: 1 percent is made up of materials that may be more than 4.5 billion years old (yes, that's billion, with a B).

That's older than the sun, according to Science magazine.

The big rock also contained some of the most important ingredients for life, such as amino acids. Scientists have long speculated that the organic matter on Earth originally was delivered by meteorite and comet impacts.

Kind of validates the saying "older than dirt," don't ya think?
