Lord Kelvin simply worked out the age of the Earth based upon heat transfer calculations. He was smart enough to know that the assumption that the Earth had no internal heat source was important to his analysis. He did live long enough to see radioactive sources discovered, but only just. Although devout, he was also smart enough to temper his beliefs about the world with science. Where it gets hard for him is when there were important discoveries yet to be made that invalidated some of his calculations. Nuclear fusion and thus the age of the sun being the obvious gap. But his beliefs were rooted in solid application of scientific knowledge as it was at the time. He wasn't a crank.
