What ancient civilization is believed to have known about Niagara Cave?

The belief that Native American tribes in the region had knowledge of Niagara Cave is rooted in the cultural connection these tribes had with the landscape around them. These groups were known to inhabit areas in proximity to what is now known as Niagara Falls and its surrounding features, including caves. They often utilized these natural resources for various purposes, whether for shelter, spiritual practices, or gathering places.

The oral histories and traditions of Native American tribes, such as the Seneca and the Iroquois, included rich narratives about the land which could encompass caves like Niagara Cave. These narratives reveal a deep understanding and reverence for the natural world, suggesting that they were aware of the cave's presence long before the arrival of European settlers.

Other civilizations, such as the Roman Empire or the Ancient Greeks, did not have direct contact with the area, and thus their knowledge of Niagara Cave would not be feasible. The early Europeans, while they explored and settled parts of North America, emerged much later in history and would not have had knowledge of the cave prior to its discovery in the 19th century. Therefore, the deep historical connection of Native American tribes to the region makes them the most credible civilization in relation to the knowledge of Niagara Cave.
