That is what the Silurian hypothesis, a scientific thought experiment, is based on. The Silurian age is a geological

nothing to do with it. Rather, the Silurian hypothesis

takes its name from a fictional species of reptilian humanoids whose civilization existed at the dawn

of human evolution, who went into hibernation in order to survive the cataclysmic event of the moon's formation

when an object or objects crashed into the young Earth around the beginning of our solar system,

flinging debris into orbit and thereby creating our earthly nightlight. Of course, the name of this fictional reptile species

was borrowed from the Silurian geological age, but that's not when any of those things happened.

And those with some working knowledge of the geologic time scale will recognize that the dawn

of humanity did not occur anywhere near the time of the

moon's formation. The moon is estimated to have taken form about 4.5 billion years ago, whereas

humankind only developed within the last 100 million years or so, whether you're counting from the appearance

of primates or the emergence of hominids. But it's close enough for the British sci-fi series

Doctor Who, which is where this fictional story was told. No offense to Doctor Who fans, I love Doctor Who, and I'm very much enjoying

Nchutigatwa's doctor. But you may be wondering what kind of scientific thought

experiment could be based on such a story. In 2018, two astrophysicists, Adam Frank and
