It is through measuring the amount of carbon-14 in an organic sample that we can find out how long ago the sample was part of a living orgainsm.
Organic materials that have been preserved in some way can be dated using this technique, called radiocarbon dating. There are limits to how far back we can look with radiocarbon dating, but it is very helpful in a lot of cases were the age of the material goes back a few tens of thousands of years.

Because it is difficult for scientists to discuss with each other and it will make scientific problems more complex.
You can't have bias because of your hypothesis. It's important to have an open mind.
No. Quality and accuracy are incredibly important to scientists. If an experiment is not performed with quality and accuracy it is not valid. However, if accuracy is not especially important, possibly because the result will be the same, then it can be ignored.
