Scientist do not KNOW with certainty how old the earth is.
FACT: In the 19th century, it was proposed that the Earth may be as much as 70 million years old. Then, certain evidence was brought to light indicating that evolution was not possible in so short a time. So, the age of the Earth was pushed back.
FACT: During the 20th century, it was thought that the age of the Earth was as much as 1 billion years old. Now, with the development of radiometric dating and the application of that technique on the meteorite "Allende", it is thought that the world is up to 4.6 billion years old. However, this is not conclusive though. The assumptions that are fundamental to radiometric dating are extremely controversial, and are not held to be reasonable by some scientists and many leading scholars. Radiometric dating is flawed in that it is founded upon a series of faulty assumptions.
Ultimately, the age of the earth cannot be proven with certainty. Whether 6,000 years or 4.6 billion years – both viewpoints (and everything in between) rests on faith and assumptions. Those who hold to 4.6 billion years trust that methods such as radiometric dating and the assumptions they make are reliable.
Now you're talking ridiculous. Assumptions have to be made in order to have a workable idea of reality. Tell me one thing that we KNOW without assumptions?
Also, you really need to understand that, to a scientist, a theory is closer to reality than a fact is. When you say something is not fact, but theory, you're really saying to me that it's closer to a description of reality.

Ridiculous? mmm
I can tell you several things we know without having to put in place an assumption as a premise.
Facts do not require assuptions.
We KNOW:
- GW Bush is president of the United States
- Queen elizabeth II is the Queen of England
Scientific fact that dont require assuptions:
- The sun rays increase melanin production in skin
-blood containing oxygen is red
-water evaporates
-water, when cooled below a certain temp, turns into ice
-the heart is the organ responsible for pumping blood through out the body
-we breathe in oxygen and breathe out carbon dioxide
The list goes on. All the above are scientific facts that we all KNOW and no one can dispute. You don’t need to assume anything to know the above with certainty. One thing all of the above have in common is that they are observable so it is fact. Science is to observe.
On the other hand you can not say that the world is 4.5 billion years old with certainty unless you were there in the begging when it began to observe. Assuming that the assumptions made in radio dating are correct then yes the earth is 4.5 billion years. But the bottom line is that it is not fact because there is a evidence to prove that the assumptions used are not valid and there is also a large amount of evidence to prove a much younger earth.

I put it to you that just like your claim that the technique used to date the earth is not accurate, perhaps the techniques that you use to observe that water evaporates (for example) are not accurate. You do not observe water evaporating directly you just observed some photons that reflected off of the water evaporating several nanoseconds ago. You ASSUME that nothing happens in between to skew your data. Just like we did not observe the creation of the Earth directly, we just observe the decay rates of radioactive isotopes that the Earth was created out of 4.5 billion years ago. Science is not only about observation, but also about inference.

I think you may need to review the meaning of the common use of the word theory.
the·o·ry (thē'ə-rē, thîr'ē)
n., pl. -ries.
-Abstract reasoning; speculation: a decision based on experience rather than theory.
-A belief or principle that guides action or assists comprehension or judgment: staked out the house on the theory that criminals usually return to the scene of the crime.
-An assumption based on limited information or knowledge; a conjecture.
fact (făkt)
n.
-Knowledge or information based on real occurrences: an account based on fact
-Something demonstrated to exist or known to have existed: Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact.
-A real occurrence; an event
-Something undisputably true or real

I dont not have to assume anything to know water evaporates. I just have to open my eyes. Have you ever boiled a pot of water?

You assume that the photons are not changed between hitting the water and reaching your eyes. You assume that your eyes convert the light into the right electrical impulses. You assume that your brain interprets these impulses correctly.

Fact is reality
What?? We're talking about the scientific use, not the common use.
It's a scientific theory, not a common definition of theory. A scientific theory describes all avaliable facts. It is a much higher held thing than a fact.
A scientist would call a common definition theory a hypothesis.

I could go on...
That is an irrational argument. So you are saying that to know that water is evaporating from a boiling pot i have to assume that my brain is really interpreting that i am seeing the vapor? come on..
So you are saying to know that blood with oxygen is red i have to assume that my eyes actually see color? So to know i exists i have to assume what? that i am not crazy? what? That just sounds like a convenient stretch to me.
Even if all knowledge requires an assumption (which it doesn’t), it does not mean that all assumptions are accurate. I happen to believe the assumptions made in order to facilitate for radio dating are not accurate. There has been in recent years the realization that radio-decay rates are not as constant as previously thought, nor are they immune to environmental influences. And this could mean that the atomic clocks are reset. However if you believe they are accurate, then good for you. But the bottom line is no one can ever know with 100% certainty how old the earth is. There is certainly a lot more evidence to prove the earth is younger.

Whoa whoa whoa. 100% certainty? Have you never taken a science course? Science is all about estimating uncertainties so we know just how accurate our measurements are.
In the case of the Earth, it is 4.55 billion years old to within about 1%, that's about 4.5 tens of millions of years error.
Significant changes to rates of radiometric decay of isotopes relevant to geological dating have never been observed under any conditions.

Capuchin, im not going to split hairs with you. The bottom line is that you have "faith" in the assumptions used for radio dating and i dont share the same faith in it. I and many other people have a valid reason to believe the assuptions are flawed. Not all scientists agree with the method which means it is not an undisputable fact.
All Scientist agree that blood that water evaporates.
