In the flood thread we have the following:

And what scientific evidence would you use to dispute the time frame?

The assumptions you have to use to begin with.
I would like to use radiocarbon dating as the main subject, as that's the one I'm most familiar with.
The primary assumption in radiocarbon dating that all organisms contained the same amount of C14 when they died. As atmospheric levels of C14 vary with cosmic radiation, and initial amounts of C14 can vary by a few percent, we need to calibrate our dates, and this is done quite successfully via tree-rings, varves and other annular data.
Another assumption is that the decay constant is and has been constant. There's no evidence to show that this is not correct.
And those seem to be all of the important assumptions!
I've seen creationists' lists with up to nine assumptions that they argue make radioactive dating inaccurate, but for radiocarbon dating those are the main assumptions we rely on.
Now, the job for ICANT and other creationists is to show that these assumptions lead to huge errors in radiocarbon dating. Simple denial is not good enough.
A good basic reference for those who are not yet familiar with the subject:
