Life != humans. The early land fossils they say they've found were photosynthesizing single-celled organisms, which seem unlikely to have evolved into humans.

Life != humans. The early land fossils they say they've found were photosynthesizing single-celled organisms, which seem unlikely to have evolved into humans. Also, Cosmos seems more interested in creating an engaging narrative for people with little to no science knowledge than delivering an accurate and complete model that best explains what we currently observe in the world. That's not a bad thing, but I'd take the details they provide as a good basic explanation but not always technically correct. For instance it bothered me when they showed discrete electrons orbiting nuclei. Electrons don't orbit, they exist in a locational probability around the atom in often surprisingly shaped clouds, that is, until observed. But I don't expect a show that's supposed to get people excited about our universe to explain convoluted tangential details that they don't need for the overall point.
