Dragons, Dead as a Dodo?

Many people use the term dead as a dodo, but the other day I was having a cup of coffee with my friends when Mike said, "Dead as a dodo.", and Cindy looked up and said, "What exactly is a dodo.". I explained to her it is an extinct bird that was flightless. She thought I was joking. Cindy is not from Missouri but she acts like it half the time. Seeing is believing.

They tell us, the dodo has been extinct since the mid-to-late 17th century or 1650 to 1699. The remains of the last known stuffed dodo had been kept in Oxford's Ashmolean Museum, but in the mid-18th century, the specimen had entirely decayed and was ordered to be discarded by the museum's curator or director in or around 1755.

So Cindy cannot see a dodo and neither can you. This picture is only a model. From the same Oxford Museum. You can see pictures and read about them and somebody could show you some bone fragments but I doubt there is any "hard scientific proof" these birds existed at all.
Our conversation changed, we began wondering if other so-called "mythological creatures" are just victims of extinction. I have always been fond of dragons and dragons are mentioned in every culture around the globe. From China to South America some dragons flew, breath fire, spoke, and could transform to appear human. So could it be that dragons are just extinct?

In the Orient dragons are commonly symbols of good luck or health and are also sometimes worshipped. Asian dragons are considered as mythical rulers of weather, specifically rain and water, and are usually depicted as guardians.

European and American Christian science claims that dragons mentioned in the book of Job are dinosaurs . The term dinosaur was not invented until 1841. They believe dragons lived at the same time as humans. The description of the Behemoth is similar to either a diplodocus or a brachiosaurus. While the Leviathan is described as a large fire-breathing water animal, just as the small bombardier beetle has an explosion-producing mechanism, or the common firefly can produce light from a chemical reaction, creation scientists speculate that the great sea-dragon may have had an explosion-producing mechanism to enable it to be a real fire breathing dragon.


So the question really isn't if dragons did or didn't exist, the question is how long before the dodo joins the ranks of the mythological creatures?
