6000 year old earth

One of the theories in Christian circles is that the earth is approximately 6000 years old. This was determined by Archbishop James Ussher and others by using the genealogies in the Bible. In places in the Bible there are lists of sons and fathers and grandfathers and great-grandfathers, etc. By searching through the Bible to find out how long each person on the genealogy list lived, it is possible to count backward to set the date of the first person at about 4000 B.C.
Evolutionists, of course, disagree with this count. They say that, using dating methods, scientists have determined the age of the earth to be about four and a half billion years old. Many of these methods use decay rates. For example, Carbon-14 is a substance found in living things. It begins to dissipate when an organism dies. By measuring how much Carbon-14 a dead organism has left, scientists can estimate how many years it has been releasing the substance, i.e. how many years it has been dead. There are a number of other dating methods. There are those who have argued that these methods are unreliable and that they are based on assumptions that may not be true such as the assumption that all these substances are released at a steady rate and that the amount absorbed while living was constant.
I would side with the evolutionists on this one. Most of the dating methods seem to correlate well. It seems unlikely that several different methods would falsely come up with the same ballpark age for the same thing. I have not seen any solid evidence that shows that oil, fossils, and sedimentary rock formations can take place quickly. Many of those who measure the age of things are doing so as part of their research. It does not make sense that they would all conspire together to misrepresent the age of the earth. Why would they? It seems probable that their information is reasonably accurate. The earth is most probably at least hundreds of thousands of years old.
