The funny thing about the "earth is 2023 years old" -claim is that it comes from christianity, more speficly 0 A.D. Because "true christian doesn't believe in evolution", but what they fail to understand, is that the "year zero" (introduced 525 AD) in Julian calendar (later replaced by the gregorian calendar) is based on the (presumed) birth-year of Jesus, not on the "birth of the world", which is why the original prefixes of the calendar are "Before Christ" and "After Christ" (Anno Domomini). It baffles me that people who claim to be deep in christianity fail to grasp this distiction in recent years. Within the bible, there is a whole books worth of events that happened before "the big J".
