For the "flood" purpose only, I will not use radio chrononlogy .... there is no need :)
Consider only Egyptian Chronology ... all Kings and dynasties are know with accurate date ...
Thus , when you see that Egyptian civilisation existed before flood ( saqara pyramid for example ) and
after the flood ... the same civilisation , with same gods , same writing system existed too ...
how is it possible if God's flood ... destroyed everything ?
Only 8 persons in the Arch ... millions of egyptian are dead ... and , just after water vanish , this civilisation
with all gods , all persons is here !!!!
Abracadabra it's magic !!!
Consider now ... minoeans civilisation ... same .. existed before flood ... and after flood :)
And as we say in "France" ... "jamais 2 sans 3" ... "Things come in threes". .. consider Chinese Civilisation ... :)
you can add , with reason, all radio chronology ... but JW will says that because there was "water" upon the atmosphere ... the quantity of C14 may differ ....
then you can only use other radio chronology but it's a little bit more complicated ... :(
