Zoroastrian texts like the Bundahishn describe a cosmology with a timeline involving a 12,000-year long struggle between good and evil. In 2024, we are nearly 3,000 years into the ealiest known history of this religion. If the “Time of Humanity” is 3,000 years, then Earth was created about 7000 BCE and we are close to

231 Generations Ago Estimating the date of Earth’s creation according to Judaic tradition involves delving into the Hebrew Bible and rabbinical interpretations. A significant historical calculation places the creation at 3761 BCE, marking the beginning of the Hebrew calendar. This date is derived from the Seder Olam Rabbah, a 2nd-century CE chronology that counts the

About 2.4 billion years ago, Cyanobacteria “hacked” the sun to split water, releasing oxygen as a byproduct and triggering the first global environmental catastrophe and subsequent biological reset.

Deep orange or reddish-brown atmosphere: The second atmosphere’s formation was crucial and occurred just before or alongside the formation of Earth’s oceans, which directly supported the evolution of organic molecules and prebiotic microenvironments. The second atmosphere began to develop around 4.5 to 4 billion years ago, as volcanic outgassing released gases trapped in the Earth’s

Likely white or grayish atmosphere: The first atmosphere developed first but was not directly involved in the development of life. The first atmosphere formed shortly after Earth’s formation around 4.5 billion years ago. This initial atmosphere was primarily composed of hydrogen and helium, the lightest and most abundant elements in the universe, which were captured from

As the Earth cooled following its formation, outgassing from volcanic activity released water vapor and other gases into the atmosphere. When the Earth’s surface cooled sufficiently, this water vapor condensed and fell as rain, filling the basins that would become oceans.

The process of salination likely began soon after the oceans formed but took hundreds of millions of years to reach the salinity levels similar to what we see today. The oceans were likely significantly salty by about 3.5 billion years ago. Salinity increased primarily through the weathering of rocks and the leaching of minerals (including

Possible lost city off Japan: Discovered in 1985 off the coast of Yonaguni, Japan, it has captivated archaeologists, geologists, and conspiracy theorists alike. Characterized by its monolithic, terraced structures, this submerged rock formation resembles architectural craftsmanship that some suggest could date back to around 8000 BCE, a time when global sea levels were significantly lower.

The feature of the epicanthic fold, particularly prevalent among East Asian populations descended from Haplogroup A, is an adaptation to cold, windy, and bright environments encountered as humans migrated northward from Africa. This phenotype likely developed to protect the eyes from frostbite and snow blindness, showcasing how genetic diversity within human lineages adapted to specific

As dairy farming became prevalent, particularly in Europe and some African communities, natural selection favored individuals who could digest lactose into adulthood. This genetic adaptation, known as lactase persistence, is a direct result of human cultural practices (dairying) and has had significant dietary implications.
