Your suggestion of this shows you have no idea how we differentiate between human designed and manufactured objects, and naturally occurring objects. It also shows a lack of knowledge about aboriginals.
I, Fester Chugabrew, am a Young Earth Creationist. I do not accept geology, or radiometric dating, or any part of modern science that might support an old Earth or evolution. Furthermore, I do not accept creation or evolution as proper objects of science in the strict sense. Lastly, VadeRetro notwithstanding, I attribute all tendencies toward verbal putzitude to be a product of those who ignore, disavow, or otherwise impugn the authority of biblical texts [08/06/2005].http://www.freerepublic.com/focus/f-news/1456767/posts?page=201#201 .
Are you saying it is scientifcally feasible to differentiate between humanly designed and non-humanly designed entities?
Also, are processes of intelligent design strictly limited to humans? IOW, are humanly devised implements the only evidence in the universe for intelligent design?
