It’s interesting that on many of the tallest mountains, all around the world, they have found fossils of sea creatures.
This got me thinking about the show ... I could not find it (I could have sworn it was one of the Naked Archaeologist shows, but not finding it). Did find this one https://tubitv.com/tv-shows/501578/s01_e07_7_noahs_ark_was_there_a_worldwide_flood which looks even older, saying the same thing. Explanation is at around the 24 min mark.
That's because geologically speaking mountain ranges like the Himalayas are comparatively young. The fossils were left there before the subduction of the two Tectonic plates created the mountains.
Most interesting! Fossil sea shells are found even at the top of Everest!
There is no doubt that the entire earth surface was covered with sea water, at one time or another. The structure of the geologic column leads me to believe that it was formed by a single flood. Additional data from the column points to the mountain ranges being formed while the sedimentary rock layers were still pliable, as follows:
Those are thick, folded, sedimentary rock layers covering the uplifted igneous or metamorphic rock.
