What you would need to demonstrate is that there are no genetic mutation and never have been any and each form of life, species, subspecies, etc. arises sui generis (created by god or whatever intelligent creator you posit in place of god) and is genetically stable for all time.
In short, your reasoning is circular.
BTW, Did you read the link I provided? Did you happen to notice the circular reasoning the evos based the mitochondrial clock on? Did you happen to notice the date range they gave to the mitochondrial eve once they recalibrated the mitochondrial clock based on empirically observed mutation rates?
