Hi Tara – not really, though I think that some of the mystical creatures may be inspired or based on real creatures. For example, the dragon may be based on giant lizards that people came across hundreds of years ago (before the species was identified). The komodo dragon is a real creature and is actually called a dragon!
No, but I sometimes wonder whether some of these myths might have there basis in some biological reality. For example, dragons sound rather a lot like dinosaurs. Dinosaurs are thought to have died out many millions of years ago, and would not have been around at the same time as people. But of course some reptiles from that period (such as crocodiles) did survive, and it seems just about conceivable that other more dragon-like creatures did survive to live alongside humans. Or perhaps ancient humans saw dinosaur fossils and tried to make sense of them.
I am pretty open-minded (some would say credulous) and I can well believe there might be creatures around somewhere on the Earth (or in the past) that we don’t yet know about that might have given rise to the myth of the Yeti, maybe even the Loch Ness Monster. I wouldn’t believe in them until I saw some very convincing evidence, though.
