How Old is the Earth SCIENTIFIC AGE OF THE EARTH. efore analyzing the arguments advanced by creation “scientists” for a very young Earth, I here summarize briefly the evidence that has convinced scientists that the Earth is 4.5 to 4.6 billion years old.

- Earth is the third planet from the Sun and the fifth largest planet in the solar system. The planet is around 4.5 billion years old, and life appeared on its surface around 3.5 billion years ago. In our universe, Earth is the only place where life is known to exist with millions of species.

How Old is the Earth According to the Bible and Science? by Rich Deem The age of the earth has been a topic of debate among Christians over the last two centuries. Several Christian ministries promote the idea that the earth is less than 10,000 years old, which they say comes from the Bible.

How Old is Earth? The oldest rocks on Earth found to date are the Acasta Gneisses in northwestern Canada near the Great Slave Lake, which are 4.03 billion years old. Rocks older than 3.5 billion years can be found on all continents.

- In a meeting in Wisconsin soon afterward, Patterson revealed the results of his study. The definitive age of the Earth is 4.550 billion years (give or take 70 million years). The current estimate for the age of the earth is 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%).

By old-Earth creationists, young- Earth creationists, scientists, and politicians. Most current estimates based on a literal interpretation of the Bible, and in particular the belief that the Hebrew word yom in Genesis refers to a 24 hour day, cluster around 6,000 years ± 2,000 years for both the age of the Earth and of the rest of the universe.

How Old is the Earth There can be no doubt about the Earth’s antiquity; the evidence is abundant, conclusive, and readily available to all who care to examine it. The best evidence is contained in the Earth’s incomplete and complex but accurate stratigraphic record — a record that has been the subject of nearly two centuries of study.

- Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one weird form or another. Indeed, some scientists think life appeared the moment our planet's environment was stable enough to support it.

How did planet Earth form? The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. Earth formed around 4.54 billion years ago by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere, but it contained almost no oxygen and would have been toxic to humans and most modern life.

How Science Figured Out the Age of Earth And the oceans have long since approached something close to a steady state, with chemical sediments removing dissolved minerals as fast as they arrive. Nevertheless, by the late 19th century the geologists included here had reached a consensus for the age of the earth of around 100 million years.

How life on Earth began Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one weird form or another. Indeed, some scientists think life appeared the moment our planet's environment was stable enough to support it. The earliest evidence for life on Earth comes from fossilized mats of cyanobacteria called stromatolites in Australia that are about 3.4 billion years old.

- A - The human race is indeed only 6,000 years old and the advancement of civilizations (languages, inventions, medical, industry, et cetera) clearly evidence this fact. However, the earth is very old. I have no problem with scientists estimating that the universe is 12 billion years old.

Geologic Time Scale The age of the Earth now is estimated to be between 5 billion and 4.7 billion years and estimates of the duration of the geologic time scale divisions have been made. Originally, geologic time scale divisions were based on the natural breaks in the stratigraphic column.

- 1 Over time, the water would be come saltier and saltier, allowing an estimate of how long this process has been going on. 2  Various geologists used this method to guess that the Earth was between 80 and 150 million years old.

If the Earth is 4.5 billion years old and humans have only been around for a few hundred thousand years, how do we know there have not been many more civilizations and species before us? The Universe is 13.7B years old. The Earth has not existed since the moment the Universe was created and is about 4.5B years old and is made out the debris of two previous generation of stars. Life on Earth started shortly after the temperatures cooled down, about 3.7B years ago. Up until 600M years ago, life was predominantly single-celled organisms. From 600M years until now, the variety of life that we see evolved. Humans started to separate from the rest of the great apes about 7M years ago and we became modern humans 200k years ago.

Atmospheric Electrostatics Editor's Note: We asked several scientists from various fields what they thought were the greatest mysteries today, and then we added a few that were on our minds, too. This article is the last of 15 in LiveScience's Greatest Mysteries series. Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one weird form or another. Indeed, some scientists think life appeared the moment our planet's environment was stable enough to support it.

How Old is the Earth To determine the age of the Solar System and the Earth, we must search for the oldest, least disturbed meteorites. K-Ar ages on stone meteorites range from about 400 million years to nearly 5 billion years, with a large concentration at 4.4 to 4.6 billion years.

- Sponsored link. The theory of evolution describes an earth that is about 4.5 billion years old. But many creation scientists interpret the Genesis account of creation as requiring an earth that is only 6,000 to 10,000 years of age. There are numerous indicators that the earth was in existence billions of years ago.

- Earth is approximately 4.55 billion years old. Radiometric dating, a method that measures the level of radioactive decay in rocks to determine how old they are has consistently aged moon rocks and meteorites at 4.4 to 4.6 billion years old.

- The age of Earth was calculated to be about 24-40 million years based on the laws of thermodynamics. Unknown at the time was that the Earth has an internal heat source (radioactive decay) In 1899, John Joly (Irish) calculated the rate of delivery of salt to the ocean.

How Do We Know the Earth Is 4.6 Billion Years Old? The Earth is very old. But how old, exactly? And how can we know with any degree of confidence? As Henry Reich describes in the video above, the process of scientifically estimating the age of the Earth revolves around, essentially, finding the oldest piece of the planet we can, then figuring out how old that piece is.

Geology Unit 3 all oceanic crust on Earth is younger than about 200 million years. This is actually surprising given that the Earth was formed about 4,600 million years ago and there are areas of the continents where the rocks are known to be almost 4,000 million years old.

By old-Earth creationists, young- Earth creationists, scientists, and politicians. Most scientific estimates of the Earth's age, based on actual measurements and calculations, are clustered around 4.5 billion years. Scientists further believe that the earth's crust solidified about 3.9 billion years ago.
