Overview
Ancient Coastal Civilization Theory
Postglacial inundation of former coastlines and the existence of submerged prehistoric sites are well established. The global quantity, character, and social complexity of the missing record cannot yet be measured, so this evidence supports a research gap rather than a civilization theory. The stronger alternative version argues that advanced coastal civilizations, possibly with global navigation, monumental architecture, astronomy, or lost technologies, were drowned after the Ice Age and remembered in flood myths. That stronger version remains unproven. The theory is worth tracking because the research gap is real, but the gap should not be treated as proof.

Claim review
The drowned global-civilization and transmission model tracked in AT-1754 is not established by the catalog's sea-level, continental-shelf, maritime, coastal-migration, or Gulf-basin evidence.
What the cited material supports
Ancient Coastal Civilization Theory is strongest as a research-warning: archaeology is biased toward surviving land, and many ancient coasts are underwater. The theory becomes weak when it treats missing evidence as proof of a lost global civilization.

Overview
Postglacial inundation of former coastlines and the existence of submerged prehistoric sites are well established. The global quantity, character, and social complexity of the missing record cannot yet be measured, so this evidence supports a research gap rather than a civilization theory. The stronger alternative version argues that advanced coastal civilizations, possibly with global navigation, monumental architecture, astronomy, or lost technologies, were drowned after the Ice Age and remembered in flood myths. That stronger version remains unproven. The theory is worth tracking because the research gap is real, but the gap should not be treated as proof.
Plain-language explanation
When the Ice Age ended, sea levels rose and many coastlines moved landward. People often live near coasts because coasts provide food, transport, water routes, and ecological diversity. That means some of the most important prehistoric sites may now be submerged. This is the strongest case for the theory. It does not require aliens or cover-ups. It simply says that archaeology has a major sampling problem. The leap comes when people claim those missing sites must have been a global maritime civilization.
Historical and scholarly context
Sea-level rise is real
Postglacial sea-level rise changed coastlines worldwide. This is a strong geological anchor.
Coastal people can be archaeologically invisible
Shell middens, camps, boats, wooden structures, and early shoreline settlements can be hard to preserve or recover underwater.
Underwater archaeology is difficult
Surveying submerged landscapes is expensive, technically challenging, and unevenly distributed. Lack of discovery in a region may reflect limited search.
What the evidence supports
- Postglacial sea-level rise and drowned landscapes are well supported.
- Coastal migration and coastal resource use are increasingly important in archaeology.
- Underwater archaeology has high future discovery potential.
Limits and disputed claims
- Drowned land does not equal drowned city.
- Natural formations are often misidentified as artificial ruins.
- Flood-myth comparison is suggestive but not decisive without local evidence.
Claim status
- Unsupported: The drowned global-civilization and transmission model tracked in AT-1754 is not established by the catalog's sea-level, continental-shelf, maritime, coastal-migration, or Gulf-basin evidence.
- Well supported: Postglacial sea-level rise and continental-shelf preservation bias make missing or submerged prehistoric coastal sites a documented research problem.
