I don't believe that we have developed a method that we can even test. When you go into a grocery store and they claim that your meat weighs 5 pounds, there's a guy that comes in there every month with a standard 5-pound weight. They don't have one and they can't possibly have one. Everyone chuckles and says that's just rhetoric. Incidentally, the same is true in a court of law.
Every courtroom is about an event in the past.
The word dinosaur is only 150 years old, but descriptions and pictures and sculpture and art of large reptiles is in every culture. The head of the Chinese museum of natural history stated in the last decade that dragons are not a part of Chinese mythology, they're a part of Chinese history. He's talking about large reptiles. If you just look at ancient cultures they all teach the same thing. The Bible teaches that large reptiles existed in the time of Job.
