One area in history that really facinates me is Doggerland:
<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Doggerland" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Doggerland</a><p>A low lying land, which was abundant with hunter gatherers, that then become flooded.<p>Not much is know about these people because their lands are now under the north sea. However I do wonder how these people shaped our history.<p>The people of Doggerland could have migrated south as their lands become flooded. which would match the timeline.
