First of all, carbon dating is only accurate to a maximum of about 40,000 to 50,000 years even if you grant the evolutionists' assumptions, so when you talk about "millions" and "billions" of years old, you're talking about radiometric dating methods such as potassium-argon, uranium-lead, chlorine-36 dating, etc.
In the case of carbon dating, talkorigins.org (the pro-evolutionist site made specifically to debunk creationism) admits there are varying amounts of C-14 in the atmosphere at a given time:
Quote:
Yes, the atmospheric content of carbon-14 can vary somewhat. The dipole moment of the earth's magnetic field, sunspot activity, the Suess effect, possible nearby supernova explosions, and even ocean absorption can have some effect on the carbon-14 concentration.
Talkorigins also admits the limits of obtaining an accurate correction:
Quote:
Tree-ring data gives us a precise correction table for carbon-14 dates as far back as 8,000-9,000 years.

Beyond 8-9k years, it cannot be said to be very accurate in a large number of cases.
From Beta Analytic, Ltd., the largest radio carbon dating lab in the world, I found some delightful tidbits:
Quote:
i. Expected sample age
Labs ask clients on the expected age of the radiocarbon dating samples submitted to make sure that cross-contamination is avoided during sample processing and that no sample of substantial age (more than 10,000 years) must follow modern ones.
http://www.radiocarbon.eu/archaeology.htm
In simple English, the lab asks the client what age they want and makes sure they get it. If you say, "No, they just want to avoid cross-contamination", so your argument is that the way in which they go about this is not through their own, objective, empirical testing, but through asking the client their opinion of what age they think the sample should be? Are you serious? This is the bastion of empiricism and objective evidence you boast about all the day long?
Second, from the same source:

Radiocarbon Dating Results
Interpretation of radiocarbon dating results is not straightforward, and there are times when archaeologists deem the carbon 14 dating results “archaeologically unacceptable.” In this case, the archaeologist rejected the radiocarbon dating results upon evaluation of the chronology of the excavation site.
There are many possible reasons why radiocarbon dating results are deemed “unacceptable.” It can be that there is an underlying depositional problem, or an unsuspected contamination, or even a lab problem. In either of the cases, it is still worthwhile to carefully consider why the radiocarbon dating results were deemed unacceptable.
So if archeologists simply say, "Nah, I disagree", or "This is archeologically unacceptable" (lol), that is sufficient to reject the C-14 results, to dismiss them and throw them out the window? At the very least this proves the dating method is nowhere near definitive, otherwise this would be an impossibility (or fraud). And where I thought Creationists saying evolutionists pick and choose what dates they want was unlikely, here I see the world's largest radiocarbon dating lab admitting it right on their web page.
A good (albeit Christian) link for you to read if you care about learning about this subject is:
http://www.answersingenesis.org/arti...rove-the-bible
One of the keys to the above link is the evolutionist's necessary assumption of the truth of evolution and the corresponding old earth in order to set the constant ratio of C-12 to C-14 (1 to 1 trillion) for their calculations used in the carbon dating method. If this assumption were changed or unknown, the results would be vastly different or unknowable. And it should be pointed out that using the assumption of millions/billions of years in order to set a constant in your calculation for a dating method is begging the question (!).
Another key to the above link is in the RATE testing, if you read up about that.
Lastly, a word about the dating methods I mentioned above, which are used for obtaining the "millions" and "billions" results. If you study this, those methods are not reliable for some similar reasons radiocarbon dating isn't reliable--they depend on assumptions that no one can prove:
Quote:
Indeed, there are a number of conditions on the reliability of radiometric dating. For example, for K-Ar dating, we have the following requirements:
For this system to work as a clock, the following 4 criteria must be fulfilled:
1. The decay constant and the abundance of K40 must be known accurately.
2. There must have been no incorporation of Ar40 into the mineral at the time of crystallization or a leak of Ar40 from the mineral following crystallization.
3. The system must have remained closed for both K40 and Ar40 since the time of crystallization.
4. The relationship between the data obtained and a specific event must be known.
http://trueorigin.org/dating.asp#Why...are inaccurate
Because all dating methods demand key assumptions which cannot be proven (hence why this is "historical science", and not "science" in the sense of rock-solid, absolute, repeat-it-in-a-lab empiricism), and because evolutionists have inserted assumptions based on an earth that is billions of years old (which begs the question, assuming what needs to be proved as part of the dating method used to prove it), these methods cannot be accurate.
For more reading on the problems of these dating methods, linked below is the pro-evolutionary source (albeit presenting them in the most favorable light possible):
