No he's not right at all and you both have it backwards. A worldwide flood is an extraordinary claim and one in which should have a great deal of evidence to support it. Yet there isn't and it is known what to look for. For example, geologists can easily identify flood layers in the earth, because there is heavy mixing of rock, sediment, debris...flood layers are very obvious. They have identified these in floods that settled after only a few years, as well as matched them up with historical floods. So, if there was a worldwide flood, there should be a worldwide flood layer at the same location in the geologic column. Yet not only is there not, but there are areas with no flood layers.
But if you are looking for evidence against an event that has no evidence for it to begin with...well it's hard to disprove a negative, but in this case you can, because it's not just about the missing evidence, it's about historical civilizations that existed both before and after the flood, went on existing as if nothing happened and were not wiped out. According to most creationists and biblical historians, the flood would have happened around 4500 years ago, around 2500 BC. Archaeologists have tracked and documented the history of the Sumerians from 3300BC-1900BC, meaning they survived the flood. The Egyptians from from about 3,150BC-30BC, Mesopotamians from 6,500-539BC, Ancient Greek 2,700BC-500BC, Mayans 2,600BC-900AD, Norte Chico Civilization 3,000BC-1,800BC, Ancient Chinese 7,000BC-Unbroken all the way through several dynasties to the present! Australian Aboriginals 50,000BC-Present unbroken. There are even more that I didn't list here, but the point is, here you have a list of civilizations that we have the histories of, through archaeology by finding not just artifacts from them, but their structures, their parchments, their stone tablets inscribed, some with dated calendars like the Mayans, the Greeks, the Egyptians, who tracked their years using basic astronomy and math, who's calendars are easily understood and verified. None of these civilizations were wiped out at the time of the flood. None of them. Ancient Chinese actually has a flood story as well, except it's actually real and happened about 4,000 years ago when the Yellow river broke it's banks and destroyed pretty much all the Yao territories...but again, that was a local flood, not worldwide and did not wipe out Ancient Chinese civilization. Chinese culture is probably one of the most well documented, as they were writing and reading, recording history, long before anyone else and again...did not suddenly stop 4500 years ago. Instead their great civilization and history went on, unbroken, all the way until the present.
So if you want evidence that the worldwide flood did not happen...that's it right there, dozens of ancient civilizations that were not wiped out, that went on recording history and make no mention of a global flood. So...for you and Hockeycowboy...what's you answer to these archaeological facts?
