what is the age of the earth?

Question

no one knows just how the earth was formed.no one has a perfect answer for this question.i hope u all give a perfet or sensible answer for this.

Answer 1

No, no one knows a perfect answer, but plenty of people have enough sense to try to deduce things.

The Big Bang theory is the best working model for the formation of the solar system

Using U238-Pb206 dating on meteorites on rocks on Earth the age of Earth itself is around 4.55 billion years old.

I believe in God, too. I also believe that we were allowed to evolve reason and intellect to USE them.

Answer 2

The earth was formed approximately 4.55 billion years ago. This age is based on radiometric dating of meteorites that probably represent the approximate age of the formation of the solar system.

Scientists have been able to piece togehter the early history of the earth using physics, astronomy, and geology. From the wikipedia article "Earth" (link below):

"Scientists have been able to reconstruct detailed information about the planet's past. Earth and the other planets in the Solar System formed 4.54 billion years ago[7] out of the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun. Initially molten, the outer layer of the planet Earth cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object (sometimes called Theia) with about 10% of the Earth's mass[16] impacting the Earth in a glancing blow.[17] Some of this object's mass would have merged with the Earth and a portion would have been ejected into space, but enough material would have been sent into orbit to form the Moon."

The statements above a NOT a guess, NOT an assumption, but a model based on thousands of observations by thousands of scientists.

BTW...I'm a Christian and a geologist and one CAN do both. Check out the link below on "Radiometric Dating from a Christian Perspective" that explains how radiometric dating methods work and why they are pretty trustworth.

Answer 3

Several lines of investigation indicate an age of 4.5 or 4.6 billion years for the raw materials, and about 3.5-4 billion for the oldest crust (rocks).

The legends from ancient civilizations that have been handed down by uninformed storytellers and speculators would suggest the earth is only a few thousand years old; that is patently ridiculous as your own eyes can tell you that some processes have obviously been going on for millions of years if not longer. Never substitute ancient myths and legends for demonstrable scientific fact -- that is just foolish, and/or wishful thinking.

Answer 4

One can take the atitude that there is no perfect answer to any question, and no proof of anything. Go to philosophy on that one. Even eyewitness accounts of crimes frequently vary in some significant details.

There is NO perfect answer to anything, really.

As to the age of the earth, a wealth of evidence suggests an age of billions of years. More precise estimates come from radiometric dating, with very good data indicating the formation of the planets in our solar system on the order of 4.5 to 4.6 billion (thousand million) years ago.

The answer is not perfect, and perhaps it is wrong, but based on human knowledge as it exists today, this estimate is the most probable. No one was there, so we will never really know, will we? I am satisfied with that answer, however, and so are most people with knowledge in that area.

Answer 5

I believe in a young Earth. Science has some very good evidence that says the Earth is 4.56 billion years old, but Christians say that they can add up the age of everybody in the Bible and guess at how long the gaps are and it is only about 6,000 years old so God must have made the world look much older to trick all the scientists.

But both are wrong. The world was created last Tuesday morning, including you, but we were created with memories that make us think we've been here longer. Really, look it up on Google. It's called "Last Tuesdayism" and many scientists and Christians see that it must be true.

But don't pay any attention to a group called Last Thursdayists, they are just a bunch of wierdos with ridiculous ideas and no evodence to back up their myths..

Answer 6

Don't know why you assume what you, but we do have knowledge on how the Earth was formed. We also know how old Earth is. Of course we cant know it to the minute. And it depends on how people define age of a planet.

Perfect? Very little in life that is prefect.

Answer 7

No one knows? Better go to the library. Most estimates put earth at a minimum of 3.5 billion years. There is some speculation that it may in fact be older. Rock (strata) have been dated to 3.5 billion. To say that no one knows, is turning a blind eye to the research of many generations.

Answer 8

The best estimates using some elements radioactive decay is ...
► 4.5x10^9 ±5% years.

Answer 9

4600 Million years

Answer 10

it is said that the earth was formed 4.6 to 6.4 billion years ago during the "big bang" i think....
