A young-Earther would object to all of the "assumptions" listed above.However, the test for these assumptions is the plot of the data itself.

Below is a table of radiometric ages derived from groups of meteorites: As shown in the table, there is excellent agreement on about 4.5 billion years, between several meteorites and by several different dating methods.While these values do not compute an age for the Earth, they do establish a lower limit (the Earth must be at least as old as any formation on it).This lower limit is at least concordant with the independently derived figure of 4.55 billion years for the Earth's actual age.The higher the uranium-to-lead ratio of a rock, the more the Pb-206/Pb-204 and Pb-207/Pb-204 values will change with time.If the source of the solar system was also uniformly distributed with respect to uranium isotope ratios, then the data points will always fall on a single line.

Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.
