How old is the Earth and how did it get hear?

Answer 1

.... 4 Million years ago a speck of space dust hit amoeba in frozen slush resulting in Monkey embryos that evolved into what you see today OR you can read the Bible and find that GOD created everything you see because he could. Look at the moon & stars tonight ... He really is something huh? As far as how old the Earth is ....at least 6000 yrs old. No worries though...His power is still able to keep it together for another 6 or 60000000 years if he wishes. Good Question

Answer 2

If you want the religous answer, even that is debated. The sceintific answer is not (well, not much anyways. scientists do love to argue though!).

Geologists can use a multitude of dating techniques to age the earth with great accuracy. The Earth is approximatly 4.55 Billion years old, give or take 1%. The rocks with the oldest age (meaning the oldest age that they existed in their current state, which can be changed by things like geological events, some rocks are quiet young) have been dated to 4.1 billion years, meaning the earth is at the very least that old. Most methods to get an upper limit of the age of the earth(and the solar system) use the rate of radioactive decay, and have consistandly found that the earth, and the solar system, must be approximatly 4.55 billion years old.

The earth got here the same way all the other planets did! Billions of years ago some giant star went supernova, leaving a bunch of gases and stuff in space. Because of gravitational effects, this gas formed into clouds, which eventually compressed even more, and clouds started comming together. This is how the sun formed, by a bunch of gasses collecting together, into a bigger and bigger (and heavier and heavier, and therfore with a stronger gravitational field) until it formed a star. If there wasn't enough stuff around it, it would have formed a smaller star, like a brown dwarf, which is not hot enough to support life. Lucky for us it grew into a nice yellow star!

When the star formed, a disk (like the rings of saturn) or dust formed around it, and the planets formed out of this ring. They startd, like the sun, as smalled things that grew larger. The early solar system had lots of rocks and gases floating around, and when the collided them sometimes stuck together, and when the planets got a big bigger, their gravity pulled in even more stuff. now space is mostly empty, with most of the stuff haveing been sucked into the planets, though lots of comets and asteroids still float around out there! Nobody can 100% prove this to be what happened, but then again, we can't 100% prove anything. But all evidence strongly suggest it went something like that, and observations of other stars support the idea.

And here we are now, orbiting at 90 miles a second, so it's rekoned, the sun that is the source of all our power!

Answer 3

The Earth is commonly believed to be about four billion years old by most scientists, but this is yet to be irrefutably proved. It is also commonly believed that our entire solar system - the Sun and all its planets - are formed from the dust from the explosion of a previous star which formed shortly after the Big Bang.

During the formation of the solar system, the cloud of very hot rotating dust seperated into ten bands and a clump in the middle. These became the planets and the asteroid belts, while the clump became the Sun. The moon is thought to have been captured after the earth had formed into a sphere, but before it had cooled to a solid.

Answer 4

4.5 billion years.

Billions of years before that stars were created, only because the universe was precisely "tuned" at its' creation to allow that. While they burned, they formed all the elements. When they ended, some exploded, scattering those elements far and wide. Some gathered together under gravity and formed the Earth.

We are the stuff of exploding stars, gathered together in this tiny place in a most unlikely and fortunate way. Truly awesome. If someone says a higher started the whole process, and still watches over us today, I say that's one good explanation, and there is no scientific fact to contradict him.

Science actually has produced a far more awe inspiring story than that this all flashed into existence a few thousand years ago. The process was far more spectacular and far more interesting than that. There was no need to create useless fossils to "test our faith". The real ones of our distant ancestors are part of the awesome process, and can inspire faith, rather than test it.

Answer 5

The generally accepted age for the Earth and the rest of the solar system is about 4.55 billion years (plus or minus about 1%). This value is derived from several different lines of evidence.

This one of the theories speculating the age of the earth. There are so many theories related to age of the earth however none is conclusive so far. God only knows.

Answer 6

ya i can answer u clearly... the exact age of earth is proved to be 4.5 billion years.... that's right.. but the oldest aged fossil is found to be around 3.8 billion years old and this is 'cause an asteriod hit the earth when it's just 800 million years old ,,. it became molten and also during this impact the moon was formed... but the earth was formed along with the other objects including the asteriods... by the radio carbon dating it is found that their age to be 4.5 billion years... asteriods are one of the oldest ones in our solarsystem....


to be more precise the age of our reformed earth is 3.8 billion years but it true age is 4.5 billion years

Answer 7

About 4 1/2 billion years old..
Accumulation of dirt, meteors, comets, rocks & junk orbiting
around the primordial sun ....

Answer 8

Read a science book. Nobody knows although there are promising theories on planet formation.

Don't read the bible. Its fiction, philosophy at best, that shouldn't be used to teach science. The bible serves its purpose for people of faith, but it shouldn't be used as scientific reference.

Answer 9

The starting formation of the earth is about 5.6 billion years ago. It got finished at about 4.6 billion years ago.

Answer 10

That's a mighty big question with two answers.

1) Science can tell us the age/the how.

2) Religion can tell us the why.

Good luck for the argument between creation and science!
