YECs are fond of trying to find little difficulties in age issues, but rather than endlessly refuting them, l thought, what would a YEC lake deposit show, such as in Lake Malawi which is quite deep, with anoxic deposits which have no bioturbation?
YEC with rapid radioactive decay in the Flood year would show more or less linear increase in C14 age with depth of deposit to about 4500 years or less if the lake is younger. Older lakes with Flood deposits would then show a rapid increase to 50,000 as you struck them.
Any tephra layers would also have very high age.
Any biotic remains would be of plants and animals from many geologic periods.
In contrast, Lake Malawi has many C14 dates, 3 tephra, and some magnetic chronology dates all falling on a line linearly increasing with depth to a date in excess of 1,000,000 years.
That would seem to falsify YEC.
Any flaws in the argument? My wife's church is hosting CMI in three months and l hope to be able to ask some pertinent questions.
