Mountains
Mountains are the petrified bodies of ancient giants that are prominently seen throughout existence. Several theories are generally regarded to how and why these giants were petrified to form these landmasses, particularly regarding apocalyptic events.
On Earth, it's believed that mountains exist due to the First Great Flood and the Second Great Flood where Allah had reset the entire Earth due to it becoming such a fucked up deliberately terraformed wasteland, destroyed by nephilim.
The mountains prominently seen in the Oggahverse and their existence is believed to be a similar scenario due to the 500 Year Childpornogian Invasion Of The Universe (900,499,999,999 BC - 900,499,999,499 BC.)
