Rigveda Samhita, Veda Book 1 of 4

The Rigveda, Sanskrit for “praise knowledge”, is a collection of sacred texts of Hinduism first written down between 1700 and 1100 BCE. The sounds and texts of Rigveda have been orally transmitted since at least circa 2000 BCE. It discusses cosmology, praises deities, and covers philosophical questions including… 1.164.34: “What is the ultimate limit of […]

Neolithic Revolution

468 Generations Ago (from 2020 CE) The Neolithic Revolution is the earliest known Agricultural Revolution. It is very likely that humans practiced forms of agriculture earlier. How much earlier? Well, without evidence, we are guessing. For convenience, anthropologists label humans as hunter-gatherers prior to the Neolithic Revolution. The fact is that the current theory states

Successful Out of Africa Migration

Through minor DNA changes, we know which early humans have descendants alive today. This successful “out of Africa” migration, the Southern Dispersal, took place around 70,000 to 50,000 BCE. Our ancestors proceeded to colonize all the continents and larger islands, arriving in… Eurasia circa 60,000 BCE Australia circa 65,000 BCE South America circa 30,000 BCE

Plate Tectonics

By dating rocks and fossils scientists can document the movement of the continents over time.  To confirm and refine this science, geologists study rocks, paleontologists study fossils, and anthropologists study human societies, cultures, and relics. The location and dating of rocks, fossils, and relics allow us to understand the distant past. Cynognathus, circa 242 million

Purgatorius — Earliest known proto-primate.

Within mammals, only primates have binocular vision, grasping hands, and flat nails–instead of claws. Purgatorius might have had all three earning it the earliest known proto-primate label. It lived in Eastern Montana about 66 million years ago during the very last years of the Cretaceous period. It lived through the K-T extinction event and the extinction

Hyoid Bone: Speach Emerges

Around 700,000 years ago, the development of a human-like hyoid bone suggests early hominins may have begun transitioning from simple vocalizations to more structured speech. This period marks a critical evolutionary point for Homo heidelbergensis, whose anatomical adaptations for speech, coupled with advanced tool use and complex social structures, indicate possible use of rudimentary language.

4004 BCE, The Bible’s Earth Creation Date

240 Generations Ago Interpreting the date God created the Earth by reading and interpreting the Bible is very difficult. You can put dates on events, time between events, etc. then convert it to the modern Julian calendar. One popular interpretation is Sunday, October 23, 4004 BCE. Generating this date, and similar, rely on the Ussher

Homo neanderthalensis: Verified True Symbolic Thought

16,000 Generations Ago True symbolic thought emerges before 430,000 BCE: The discovery in 2018 of Neanderthal art dating back to 68,000 years ago, proved symbolic thought in Neanderthals. It also indicates strongly that symbolic thought evolved in or before our common ancestor about 430,000 years ago. This must be true unless either they evolved it

Jericho Founded

360 Generations Ago Earliest known permanent settlement in the Africa/Middle East zone.  Jericho, located in the West Bank, Palestinian Territories, stands as one of the earliest known permanent settlements in the Africa/Middle East zone, with continuous habitation dating back to at least the 9th millennium BCE. Situated near an oasis in the Jordan Valley, Jericho’s

Radiometric Dating

5 Generations Ago In 1905, radiometric dating was discovered. It is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. This technique is used to date rocks. Paleontologists regularly order discoveries in chronological order and estimate their age. Knowing the age of rocks allows paleontologists to assign known
