Dr. Brian Cox

As previously mentioned, it’s good to see the rising popularity of astrophysicist Dr. Brian Cox.

In this video, he explains that life on Earth is about 4 billion years old, but for the first 3 billion, there was nothing more complicated than single celled organisms. He suggests that this may be the reason that civilizations are rare in the universe, i.e., that they’re only around for the blink of an eye in terms of geologic time.

To me, it also makes one wonder why it took God 3 billion years to create the first multicelled form of life.
