In Revelation 12, an account is given of a metaphorical reference back to Mary giving birth to Jesus. She is, according to the account, "given wings like an eagle" to fly anywhere, while a dragon — the Antichrist — tries to fight against heaven, is cast out, and then tries to pursue Mary instead. The dragon, however, couldn't get close due to the eagle-like wings, so decides instead to unleash a flood from its mouth (Revelation 12:15)
What's significant about this passage is where else it's echoed. You certainly don't see watery rivers coming from beastly dragons' mouths in any pagan sources of the ancient Near East of this time. It's absent from Greek, Sumerian, Egyptian, Roman, every source you can think of from that time and place.
Notice how I said and place, however. There are indeed sources from other cultures that mirror it. Why haven't we noticed it? Because these cultures that possessed eschatology mirroring this account were nowhere close to the location where events like the death and resurrection of Jesus were occurring. No, these mirror accounts, beastly images that bear a startling resemblance to this, are from thousands of miles away.
Long before Europeans arrived in the Americas, what is now Mexico was home to Native American civilizations that, independent from everything else going on, were building their own pyramids. They were astounding astronomers, and using the information they gathered from the heavens, they conjured up a calendar system with prophesies tied to it. They were the Mayans, and what images do their codices mention as something that would happen when the world ends? That very same image of a flood coming from the mouth of a dragon-like beast.
Here's even more proof of Biblical truth: For two distinct cultures from opposite corners of the world, mind you, to somehow manage to conjure up identical eschatological images, either their cultures intermingled — which we know did not happen, because there's absolutely no ancient Jewish, Roman, or Greek accounts of a world being known this far away from their empires — or there is indeed a God who managed to give two distinct portions of the world identical images of how He would return.
Of course, the Mayans were indeed pagans, but that's beside the point: By being the creator, the only creator, of the cosmos, there's no doubt the God of Christianity, Judaism, and Islam would have planted some object in the sky that cultures thousands of miles away from each other would be able to interpret the same way.
Hopefully people see this as even more evidence that the Bible is true. Because two prophesies thousands of miles away from each other that tell about the same thing can't possibly be mere coincidence.
