Lost lands are islands or continents believed by some to have existed during prehistory, but to have since disappeared as a result of catastrophic geological phenomena.
Legends of lost lands often originated as scholarly or scientific theories, only to be picked up by writers and individuals outside the academy.
Occult and New Age writers have made use of lost lands, as have subaltern peoples.
[citation needed] With the development of plate tectonic simulation software, new lost land has been discovered and confirmed by the scientific community (like Greater Adria in 2019).
Although the existence of lost continents in the above sense is mythical (aside from Zealandia[1] and Greater Adria[2]), there were many places on Earth that were once dry land, but submerged after the ice age around 10,000 BCE due to rising sea levels, and possibly were the basis for Neolithic and Bronze Age flood myths.
