"The age of the fossil matrix can be determined by other proven dating methods such as potassium/argon."

Potassium/argon dating - based on assumptions (hardly scientific) How ever does one know the starting point or any events that may affected the levels of potassium/argon in any given sample? They don't, more assumptions and speculation.

Assumed all the argon gas escaped during formation, the initial amount of argon gas - assumes it was zero, assumes any argon gas found is a result of the radioactive decay of potassium, assumed the portion of the rock he's testing was sealed avoiding contamination, etc, etc.
So why don't you tell me which events could affect the level of radioactivity and it's decay in a sample. One doesn't need to be a physicist to see the gaping assumption holes in potassium argon dating.
Evolutionism is not scientific, it is a religion with the label "science" slapped on it. But since you seem to believe it is falsifiable, why don't you give an example of a single cell organism "evolving" into a mammal - be sure to include pictures as medicine can for its theories after all you are attempting to equate your religion with medicine.
