    $\begingroup$ Ugh. A large part of Europe (southern Spain, most of Italy, most of Greece and the Balkans, almost all of Hungary, part of Romania, southern Ukraine etc.) was under the sea (the Thetys Ocean, the Parathetys Sea, the Pannonian Sea) until 5 to 10 million years ago. Today those places have lofty mountains, rolling hills, and fertile plains. People realized that they are walking on what was once the bottom of the sea only towards the end of the 19th century. $\endgroup$

  • $\begingroup$ Just follow the links in my comment and see where those sea were, and when they dried out. Or find a map of Europe in the Miocene period. $\endgroup$

  • $\begingroup$ Why does the ocean water have to be salty? It is salty on Earth because the Earth has a lot of salt to dissolve in the first place. Yet there are many very ancient lakes that are not at all salty. That's because they are in areas that are relatively salt-free. So just make your planet salt-free. $\endgroup$
