Until the middle Pleistocene, Britain was a peninsula of Europe, connected by the massive chalk Weald–Artois Anticline across the Straits of Dover.During the Anglian glaciation, approximately 450,000 years ago, an ice sheet filled much of the North Sea, with a large proglacial lake in the southern part fed by the Rhine, Scheldt and Thames river systems.
It was probably a rich habitat with human habitation in the Mesolithic period,[2] although rising sea levels gradually reduced it to low-lying islands before its final submergence, possibly following a tsunami caused by the Storegga Slide.[3]
Ok that is more in line with my understanding of the history,
and with common sense.
The "flood" that ripped Britain away from the mainland has
as improbable a sound as that the sea burst thro' the
Dardanelles and roared into the Black Sea.
