You're excused.
I don't know why you posted that link but it was peripheral to the entire topic OTHER THAN it somewhat negated the idea that the heat was from the initial formation. It explained nothing about the heating of the Earth other than mentioning radiation in passing as the reason. It did not provide any information on how radiation might be responsible or for how much.

In addition you claimed that NONE of the heating was from the initial formation which is blatantly false according to all the references I've consulted. The original link and the Scientific American Link discuss the three primary items responsible for the heating, one of them being heat from the initial formation.


Oh and the initial link I provided explained the heat sources so again I'm not sure why you went off on the Kelvin thing about calculating the age of the Earth.
