Where in evolutionary theory does it say that "...snow has been piling up in Greenland since the beginning of the Earth at a uniform rate..."? You say that this is constantly claimed. Where is this claimed constantly (not that your statement implies many such clamis)? Refereed literature reference required.
That was the premise of Jennyp's post which you were trying to back up. Further, evolutionist assumptions are indeed based on uniformitarianism - that all their measurements of today can be extended back without modification as far as they wish. I am glad you agree with me that such assumptions by evolutionists are utterly ridiculous.
