Abstract. We focus on one of the most important events in human history, the 4.2 kiloyear event, when great civilisations around the world collapsed into anarchy and social chaos. From this moment on, climate cooling and widespread aridification began, lowering agricultural food production and human living conditions. Various hypotheses exist about its cause; the most promising approach links the 4.2 kiloyear event to a cosmic asteroid crash into Mesopotamia. The asteroid landed in a densely populated area; we examine at first major translations of preserved Sumerian documents on details and progression of this catastrophic event. We quote major impact features as observed by historical Sumerian eyewitnesses. The impact, as a full strike, eradicated the Imperial city of Akkad. The impact damaged all other Sumerian towns to different degrees. Based on our findings, we identify the location of the missing city of Akkad. We analyse the onset of global cooling and severe aridification in the framework of our cosmic climate footprint analysis for a selected 1,000 year timeframe. This footprint analysis of Holocene climate change affirms the occurrence and date of the impact event.
We also identify volcanic mega-‐‑eruptions, which are responsible for multi-‐‑decadal global temperature dips but which cannot cause centennial-‐‑long climate changes.
The footprint analysis takes 5 climate macroforcings into account and explains global cooling and aridification based on impact-‐‑related causes.

If you want to discuss those, please provide links. There is plenty of evidence to support a global flood, and many have discussed it. Hancock alone talks about all sorts of evidence, and he's not coming from a Christian viewpoint.

That's opinion, not science. Claiming that all creationists lie and twist the facts doesn't make it so. I could make the ame claim about evolutionists, and you'd call it a lie, so you have to do better than that.
Assuming that every old culture on earth has a global flood legend because they were all stupid and didn't know a bad flood from a worldwide one is arrogant.
Just because people were ancient doesn't mean they were stupid. With all of the evidence of advanced capabilities in really ancient people, it's not even logical.
Can you admit that the only reason you don't accept a global flood as possible is because it's in a Bible story? If it was everywhere else and not in the Bible, I'd bet you would be far more willing to accept it.

It's an opinion informed by and supported by science though. The only thing supporting a global flood is ancient myths. Looking at the geology alone shatters it in 10 seconds or less.

And conversely, assuming that there was a global flood based on the limited frames of reference of ancient people is both ignorant and reeking of confirmation bias. The fact is, the only "evidence" and I loathe to use the term in this context, but the only thing that is used to support this global flood is the myths of ancient people. The fact
Of the matter though is that there is no confirmation of this anywhere in the geologic record anywhere in the world. If I were writing a paper and presenting it to publishers, I would have to have multiple corroborations supporting the science from more than one discipline and it would have to be capable of passing muster by having my data independently reproduced or corroborated. . You have to look at the context of relying on ancient flood myths as well. Most of the versions floating about the Fertile Crescent and Levant all share one point of origin so they really aren't different cultures or societies presenting corroborating account. All of the cultures presenting a flood myth had their societies based around important water sources. The Tigris and Euphrates, the Indus, the Nile are all prominent examples and these rivers flooded annually. Sometimes catastrophically and there were other events occurring in the region that added even more devastating events for these people. All it takes is one massive event and the resulting diaspora to spread a story far and wide. It doesn't make it global though.

Nobody is saying they were stupid. It doesn't mean though that Mesopotamians for example, were aware of geological events in Europe or North America. Their entire world, was the Fertile Crescent. So to them, the entire world would have flooded. That's not the same as an actual global flood event for which there is no evidence for outside of ancient Myths like the Epic of Gilgamesh which was the direct influence for Hebrew flood stories a la Noah. There's no argument at all about devastating periodic flood events that were localized to some of these cultures based around rivers where annual flooding was the source of their agricultural growth and that the resulting diasporas helped spread the stories. It's not the same as a singular world wide event though.

I can't speak for Barcs but if there was any actual physical, scientific, geologic evidence to support the notion then there would be a conversation to be had. There isn't though.

I have yet to hear an explanation that doesn't include a global flood for polystrate fossils. We don't see fossils forming today in lake beds, either. Clastic dikes present issues. There are other issues in other areas, too, that don't fit well in the traditional theories, that exclude a global flood.
Some creationist presentations include claims about "polystrate fossils". From the description, this term is used for fossils which intersect several beds (layers), usually in sedimentary rocks. Although often used in creationist literature, I have been unable to determine the origin of the term -- it is not a standard geological term. This makes it difficult for the uninitiated to find conventional literature about these fossils.
Are "polystrate" fossils a problem for conventional geology?
Well, they were not a problem to explain in the 19th century, and are still not a problem now. John William Dawson (1868) described a classic Carboniferous-age locality at Joggins, Nova Scotia, where there are upright giant lycopod trees up to a few metres tall preserved mainly in river-deposited sandstones. These trees have extensive root systems with rootlets that penetrate into the underlying sediment, which is either a coal seam (i.e. compressed plant material), or an intensely-rooted sandstone or mudstone (i.e. a soil horizon). Dawson considered and rejected anything but an in situ formation for these fossils, and his interpretation is closely similar to current interpretations of sediments deposited on river floodplains. An interesting feature of these examples is the presence of vertebrate fossils (mostly small reptiles) within the infilling of the stumps.
The reason I am using Dawson rather than a more recent reference is to emphasize that many supposed "problems" with conventional geology were solved more than 100 years ago using very basic principles. The people suggesting these "problems" exist are so out of date that even 19th-century literature refutes their presentations.
