Something to THINK about
Let's assume that15.000 years ago, the last Ice Age ended. A huge amount of water flooded the world and sea-levels rose more than 100 meters. The waters rose gradually, but it happened, that lakes of melted water, broke their icy border and created hughe tsunami's. The rising sea-level caused a break-through in the Meditteranean. The existing inland-lake turned into the Black Sea, flooding a populated area and causing mass-migrations.
In 15.000 BC. one could walk from Denmark to Scotland. A time when mammoths and giant deer roamed the North Sea.
