That test Dr. Austin tested was a closed system and cannot be altered by any machine or K-Ar dating method. Once the natural occurring argon escape the system close and started forming or should start forming the daughter isotopes, i.e., argon, from potassium and ten years after the system closed or reset to zero they’ve tested the rock and it gives them 350,000 years in just 10 years. It was a blind test from an independent lab.
“These were submitted for potassium-argon analysis to Geochron Laboratories of Cambridge, MA, a high quality, professional radioisotope dating laboratory.”
Use your common sense, in just 10 years it yields 350,000 years. That’s 35,000 per year. So, if you divide Lucy’s age, i.e., 3,200,000 years old to 35,000/yr. you should see 91.42 years only and not the 3,200,000 years and that would make Lucy an ape and not a human.
