Scientists determine age of some of the oldest human bones Some of the oldest human remains ever unearthed are the Omo One bones found in Ethiopia. For decades, their precise age has been debated, but a new study argues they're around 233,000 years old.
Lomekwi 3 is the name of an archaeological site in Kenya where ancient stone tools have been discovered dating to 3.3 million years ago, which make them the oldest ever found. Lomekwi is near the west bank of Lake Turkana, which is pictured in green on this satellite image.
While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago. Civilization as we know it is only about 6,000 years old, and industrialization started in the earnest only in the 1800s.
World's Oldest Water Lies At The Bottom Of A Canadian Mine And Is 2 Billion Years Old.
One study suggested that the "Methuselah Star" is older than the Universe itself. The Universe is thought to be 13.797 billion years old, with an uncertainty of ±0.023 billion years. In 2013, a measurement of the "Methuselah Star" suggested that it is 14.45 billion years old — older than the age of the Universe.

A comb jelly. The evolutionary history of the comb jelly has revealed surprising clues about Earth's first animal.
Microscopic grains of dead stars are the oldest known material on the planet — older than the moon, Earth and the solar system itself. By examining chemical clues in a meteorite's mineral dust, researchers have determined the most ancient grains are 7 billion years old — about half as old as the universe.
The First Humans
One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
Bones of primitive Homo sapiens first appear 300,000 years ago in Africa, with brains as large or larger than ours. They're followed by anatomically modern Homo sapiens at least 200,000 years ago, and brain shape became essentially modern by at least 100,000 years ago.
Once the early rain of comets and asteroids upon the Earth subsided somewhat, subsequent impacts may well have delivered the water and carbon-based molecules to the Earth's surface - thus providing the building blocks of life itself.
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
The earliest time of the Earth is called the Hadean and refers to a period of time for which we have no rock record, and the Archean followed, which corresponds to the ages of the oldest known rocks on earth. These, with the Proterozoic Eon are called the Precambrian Eon.
What does this mean exactly? It suggests that most of Earth's water was on the surface at that time, during the Archean Eon between 2.5 and 4 billion years ago, with much less in the mantle. The planet's surface may have been virtually completely covered by water, with no land masses at all.
Nevertheless, it means that each time you take a sip of water, you are drinking from a 4.5 billion year-old font that dates back to the formation of the Solar System.
Earth has vast oceans today, but our planet was a dry rock when it first formed — and water was a late addition, rained down in asteroids from the icy outer solar system.
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been told by physicists for the past several decades.
A galaxy named HD1 has been crowned the new farthest object in the cosmos. Located some 13.5 billion light-years away, HD1 existed only about 330 million years after the Big Bang.
Scientists looking into the origin of life on Earth have claimed that the water present on the planet is very, very old. In fact, a new study has said that it's older than the Sun. The research is based on the discovery of water vapour around V883 Orionis, a young star, 1,305 light years away from Earth.
A new study reveals that the water in our Solar System is really, really old – older even than the sun.
Ballentine said the water is not drinkable, but admitted, “the water is crystal clear when it first comes out of the rock and looks very tempting.” Lollar is quick to deny full-on drinking these ancient waters – she's literally just talking about putting the tip of her finger to the tip of her tongue.
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means 'upright man' in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.
