Of course your analogy fails because it conflates universal flood accounts [(which align with geological evidence like continent-spanning sedimentary layers and marine fossils on mountains (Geisler, I Don't Have Enough Faith to Be an Atheist)] with disparate mythological tropes. Flood narratives (e.g., Mesopotamian, Native American) share specific details with Genesis (global deluge, survival via vessel, and divine judgment), unlike dragon or sun myths, which lack such consistency and empirical corroboration. As William Craig notes in his work, A Reasonable Response, the Flood's geological and cross-cultural evidence meets historiographical criteria for establishing reliability.
Nah, there's plenty of corroboration of dragon and sun god accounts. Otherwise, why would there be fossils of giant creatures buried in the ground? Or historical stories of people battling giant reptiles? Or Christian saints who famously slew them? Not to mention the hundreds of sun deities attested to at religious sites dotted across the globe?
Besides, the Genesis account is consistent with dragons. At least that's what creationists argue. You can find the argument that dinosaurs breathed fire and were actually dragons in:

And literally dozens of others, if you have the time and inclination to do the research.
Here's a pretty typical write-up, from Apologetics Press (
Discover Magazine, July 2007):
" There are three reasons the creationist should have no problem believing in the possibility of an animal breathing fire. First, an all-knowing, all-powerful God who created the Universe out of nothing and life from non-life would have no problem making an animal that could breathe fire. Second, God created many creatures with remarkable qualities, including the electric eel and the bombardier beetle (which can shoot a harmful, boiling-hot spray out of its backend). Couldn’t God have made a fire-breathing animal, too? Third, God said in Job 41 that, indeed, He did create a fire-breathing animal. The animal called leviathan could shoot sparks of fire from its mouth and cause smoke to go out of its nostrils (Job 41:18-21).
Those who say that no animal could ever breathe fire fail to recognize the truthfulness of the Bible and the awesomeness of God. “Is anything too hard for the Lord?” (Genesis 18:14)."
Here's the summary from another (McMurtry, 2020 -
The existence of fire breathing dragons):
"Were fire breathing dinosaurs created by God during the creation week? Did man and this kind of dinosaur exist at the same time? Could the stories of men fighting fire breathing dragons to rescue fair maidens be true?
Yes, on all counts."
Here's two professional creationists spending 40 minutes arguing Leviathan was a "fire-breathing dragon"
What is “LEVIATHAN”? The book of Job chapter 41 gives a very colorful description of a creature called “LEVIATHAN”: “Smoke goeth out of his nose.” “A flame goeth out of his mouth.” Could “LEVIATHAN” be the fire breathing dragon recorded throughout history? Join Eric Hovind and dinosaur...

You want to argue that dragons were mythical, then sort out your own house first. You could start with all the references in the Old Testament.
In contrast, isolated myths do not. The Flood's unique convergence of literary and scientific evidence distinguishes it from the arbitrary folklore that you have referenced.
It doesn't. There is no evidence consistent with a global flood.
Your "continent-spanning sedimentary layers" don't exist. The very large sedimentary layers that do exist are regional only in nature, were laid down over millions of years, don't show the types of inclusions typical of flood layers, and are generally very, very old (in the 10s to 100s of million of years).
Marine fossils on mountains are much more parsimoniously explained by geological uplift, than a catastrophic global deluge and mass extinction that somehow fails to leave a trace in the geological and fossil records.
Not to mention that if it happened any time since the onset of the Holocene then there are dozens of cultures in vastly different parts of the globe that lived through it without apparently noticing or changing. The archaeological record shows no simultaneous cultural disjuncture.
