NOTE

Water's Silent Eraser

Water possesses an incredible power to reshape landscapes and erase the remnants of ancient civilizations over extended periods. Many archaeological sites may have been lost to nature, as the erosive effects of water can consume structures and artifacts, burying them beneath sediment or even taking them to the depths of the ocean. The Grand Canyon serves as a stark example of water's transformative ability, with a seemingly insignificant river having carved out an impressive geological feature. This phenomenon suggests that numerous ancient civilizations likely remain undiscovered, submerged and eroded under the ocean's surface, highlighting the relentless force of natural elements on human history.
