Asteroids are usually referred to as being a solid rock from outer space whereas comets are usually a mixture of ice and rock and typically burn up before hitting the earth.
In 1907 a large something from outer space destroyed thousands of acres of forest in Tunguska.
Libby, the discoverer of the C14 dating method, was very disappointed with this problem.
He understood that archaeological artifacts were readily available.

National Geographic reports that scientist Dallas Abbott from Columbia University has been gathering data and announcing for the past ten years that a giant tsunami deposited ocean floor sediment on Madigascar.
Farrell, a journalist who writes for C dating) cannot place any time frame on anything close to a million years, let alone “65 million years ago.” The maximum age it can date is in tens-of-thousands of years, about a tenth of 1% of the age that Mr. Perhaps Farrell was thinking of other radiometric dating methods and simply confused them with carbon-14 dating. But if I understand what he was trying to portray in his article from which the above words were taken, I would advice him to avoid ridiculing the intelligence of a group of people with whom he disagrees in philosophy. Farrell was wrong, in one sentence, by a factor of about 1,000 times.The most widely known form of radiometric dating is carbon-14 dating.This is what archaeologists use to determine the age of human-made artifacts. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old.Scientist for the last hundred years have been searching for a crator or remnants of space rock.Finally in 2008 scientist think they have found an impact site at the bottom of a nearby lake Cheko.
