Thanks, that makes a lot more sense now lol. You did a good job explaining it.It is a very complicated answer. In order to make certain audiences and users of dating methods happy, the CE and BCE dating method became used because it did not reference Christianity. However, one of the main issues is that CE and BCE still use the birth of Christ as the basis of the calendar, they just renamed it essentially. Researchers, scientists and scholars then began to use BP (Before Present) for dating, with "Present" being 1950. The year 1950 is not completely arbitrary, as radiocarbon dating was invented in the late 1940's. BP dating is not without its issues either. Due to the atmospheric nuclear testing in the fifties, radiocarbon dates after 1950 are basically useless due to all the additional carbon in the atmosphere without a way to calibrate it.
I hope this makes sense, I was really tired when I wrote it!
