I have read an article about place where Jews crossed Red Sea. I used Google Earth to find the place. At the bottom I have seen a structure looking as a polygonal chain (photo above). Maybe it was a pipeline? After zooming, it did not look like a pipeline, but rather a wall or a some construction of this type.
I moved to the Gulf of Aden, and there were even more strange structures at the seabed.
Something like a road, traces of a snowcat or foundations of a building.
When I switch to the Indian Ocean then I saw even more interesting places. Linear structures stretched thousands of kilometers.
It looked like someone dug in the bottom of the ocean or rode on a great motorbike.
The photo below shows something like a kind of street layout.
And now the question is whether these are natural creations, or some Google Earth error, whether someone build something at the bottom currently and we do not know anything about it? It could be that in prehistoric eras there was much less water on the surface of Earth than today and those regions were above sea level and some prehistoric civilization developed there. Or it was so long time ago, that it could have been a civilistation of dinosaurs because people did not exist yet.
