Karistaer (Earth)

General Information
Earth is the third planet from the Sun and is the homeworld of Homo Sapiens. About 29.2% of Earth's surface is land consisting of continents and islands. The remaining 70.8% is covered with water, mostly by oceans, seas, gulfs, and other salt-water bodies, but also by lakes, rivers, and other fresh water, which together constitute the hydrosphere. Much of Earth's polar regions are covered in ice. Earth's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years, while its interior remains active with a solid iron inner core, a liquid outer core that generates Earth's magnetic field, and a convective mantle that drives plate tectonics.

Earth's atmosphere consists mostly of nitrogen and oxygen. More solar energy is received by tropical regions than polar regions, and is redistributed by atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. A region's climate is not only determined by latitude, but also by elevation, and by proximity to moderating oceans, among other factors. Severe weather, such as tropical cyclones, thunderstorms, and heat waves, occurs in most areas and has a large impact on life.

Earth's gravity interacts with other objects in space, especially the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Sol System and the largest and most massive of the four rocky planets.

According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties and geological history have allowed life to evolve and thrive. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions. Over 99% of all species that ever lived on Earth are extinct. Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans increasingly impact Earth's surface, hydrology, atmospheric processes and other life.

Neolithic Disappearance (The Azurity)
Around 5,900 BCE to 5,800 BCE (Now known to be 5,872 BCE), there was a noticeable drop in human skeleton and Neolithic artifacts, indicating there must have been an event which would of dropped the human population drastically. Early estimates say from 6,000 BCE to 5,700 BCE the overall human population dropped as much as 5%, and new estimates put it at 15%-35%, and most of the drops occurred in the Mediterranean and Oceania. The most plausible and most well-known theory hypothesized a mass migration movement, stating there was no mass disappearance but a mass migration and we are yet to find where they went too. Some neolithic artifacts may point to an event such as a wormhole or ancient alien civilization, such as the infamous Kotza carvings. Which seemingly depicts curved space-time with a destination at the end, which is the hypothesized shape of a wormhole, but it also seemingly depicts a strange shaped vessel above it. Another similar carving was found in Ngatea, New Zealand, which depicts another wormhole-esque object, this time without the vessel. The second most common theory is that a wormhole appeared in multiple places on earth which resulted in the disappearance.
