Just a quick comment on the below. I think the YEC response might be that
there might have been different decay rates in the past such that accross
the board radioactive decay occurred at higher rates in the past. If this
were so then the fact that the isotope ratios we see today seemt to suggest
a 770 Ma to 7 BY age would not be a coincidence. I agree though, that if
one assumes constancy or even near constancy of decay rates then the
isotopic ratios we would suggest an old earth. Just throwing out a
possible response you might get from a YEC in case you had not been aware.
