Duhhh indeed.
Any method of aging based on radioactive decay of isotopes will be based on several assumptions:
1. That each isotope will have a constant half-life (equivalent to assuming an exponential rate of decay)
2. That the total rate of creation of radioactive isotopes on Earth has remained constant between the time the fossil was formed ...[text shortened]... , it's very difficult to use carbon dating for objects that are older than 50k-60k years.

The original amount of the parent element is assumed
And it is assumed that over the supposed millions of years, no other process has worked to add or subtract either parent or daughter to or from the specimen. Talk about 'bad' science!
