iconoclastic - Despite all of the advances in engineering and computer technology, the development of a robotic hand that is as dexterous as a human hand still exceeds the grasp of modern science.
Yes. The "human hand still exceeds the grasp (pun intended?) of modern science"...at this time. In the future this may not be the case about the human hand, artificial intelligence, interstellar travel, etc. We keep making progress and we have just barely started in these areas compared to the timescale of evolution, as other posters pointed out well.
Regardless, the idea that - 'a human can or cannot make a "human hand"' still says nothing about about evolution or the argument for God. All the argument can say is that there are times humans can replicate nature, or can't (at this time). However, what we are finding out is that with some ingenuity and hard work we can often exceed nature in remarkable ways (e.g. airplanes, etc.).
The thing that bugs me the most is how this "we can't make something...therefore God" argument has been "moving the goalpost" for thousands of years. If humans do end up making a human hand, people who use this argument will simply point to something else that currently has not been achieved.
