Atheistic evolutionists are fond of using theological arguments. While they don’t believe in God, they think they know how He would not have created.
They also think that they know what is bad design and what isn’t.
Richard Dawkins, for instance, has been very vocal with his view of the backward wired retina, which actually happens to be an illustration of very good design.
However, recently biologist Steve Laufmann tried to resurrect some failed evolutionary arguments that he calls design glitches.
In addition to the above he also mentioned our supposedly weak knees, which happens to be a bizarre claim, given that humans can run a marathon, provided they train sufficiently for it.
