Assumptions are:
1. The primordial ratio of mother-daughter element can be known. It can’t.
2. The rate of radioactive decay has remained constant.
The first assumption is the one that causes some of the wild variations we see in radiometric dating.
The second assumption has been falsified.

Uranium decay to lead produces a predictable incidence of various daughter elements. The probability of a sample being contaminated with exactly the right daughter elements in exactly the right ratios is astronomically small. Multiply that by the number of samples that are found to contain exactly the same daughter elements in exactly the same ratios, and random contamination is not a rational explanation.
The second assumption has been falsified.
Radiometric decay at rates necessary to compress 4.5 billion years of apparent decay into a space of 6,000 years has never been observed, with the possible exception of a nuclear fission bomb.
I commend your patience with those who are way behind the rest of the class.
When you believe the universe is billions of years old, you will naturally chose elements with a half-life of billions of years ... which tends to produce times which are, you guessed it, billions of years.
