Not necassarily. It means that there was no worldwide flood on the earth as we know it.
I have been studying the story of Noah's Flood as a soldier in Iraq (first war). I am not an archaeologist or geologist. I am a scientist however.
We know for sure that there never was a worldwide flood. There was never enough water (2.5 billion Km^3) to raise sea levels 8 km to cover Mount Everest. There was no source for that much water. If a watery comet hit earth, it would not have been a flood but a planetary catastrophe. Look at the topography of the Persian Gulf, Iran, Arabia, and Abu Dhabi.
One can see that the Persian Gulf is a very shallow gulf with only a deep narrow submarine valley connecting Iraq to the Indian Ocean. Note that the shallow seas cover the Persian Gulf, the Strait of Hormuz (Bandar Abbas in Iran to the northern tip of Oman. That narrow strait was likely a land bridge during the Ice Age when sea levels were low enough to expose the Bering Strait Land Bridge and a land connection of Ireland, Britain, France, and Denmark. The height of the Ice Age lowered the sea levels to expose the Persian Gulf to a dry wide flat valley with a river running down the centre. The Strait of Hormuz was dry and kept Indian Ocean seawater out of that expansive plain. The land outside of the Strait of Hormuz was a shallow continental shelf. Then there was a deep trench like the one off the coast of Ice Age Florida.
As sea levels rose from 12,000 to 11,000 BCE, the narrow continental shelf water rose first, and then flooded across the Land Bridge of Hormuz (Bandar Abbas to Oman). As the water flowed and eroded the higher land of the land bridge, Flow increased. At this point, I speculate a major Richter 9 quake in a zone of common major earthquakes. This fractured the Hormuz Land Bridge opening the floodgates that filled the entire Persian-Arabian broad tectonic valley. This huge flood with an added tsunami would send water beyond the current northern shoreline of the Persian Gulf into the Mesopotamian valley.
People had been living there since 70,000 BCE. This flood inundated their "world" as they perceived it. Long afterward Semites, Elamites, and Sumerians told and retold that story. Perhaps each story was of a different family. Thus, we have Gilgamesh and the later Noah's Flood.
Alternatives to the Ice Age raised Sea Levels, Persian Gulf Flood with or without a huge quake. Possibly, there was a huge Tsunami big as the Indian Ocean Quake of December 2004 that may have worsened the situation. There was a major End Ice Age flood that rising waters of the Mediterranean overflowed the land bridge of the Bosporus separating land on which Istanbul stands on the west in Europe, and Oskudar on the East in Asia Minor.
Sea Water poured into what was (during the Height of the Ice Age) a fresh water lake (Black Lake). This rapidly poured seawater into the fresh water lake, killing fish, flooding the littoral of the entire shoreline of former Black Lake. Now it is the much larger and deeper Black Sea. Hundreds of thousands of people living along the old fresh water shoreline were drowned and another hundred thousand were forced to migrate rapidly to higher ground. Some might have even headed toward the Caucasus Mountains (say, Mount Ararat).
The least plausible is some big Nile River Flood but we have no evidence of other than the seasonal Nile Floods.
The other major flood was in Washington State at the end of the Ice Age. As the continental glacier began to melt, it formed huge lakes held back by a glacial Ice Dam. The Glacial Lake Missoula was held back by the Clark Fork and Columbia River Ice Dams. The Dam broke several times producing huge floods that covered most of Washington State and carved the gorge of the Columbia to the Pacific Ocean.
Native Americans lived there at that time and they have legends of those floods in addition to geology proof of flood basalts across central Washington. Native Americans have several different stories about the Glacial Dam (Bridge of the Gods) and the devastating flood that destroyed many villages and animal herds. It was an American equivalent and probably occurred near the same time as the Mythical Noah's Flood.
Summary: Noah's flood was possibly a regional flood but never a world flood. The legends were based on a real local event.
