The eponymous Silurians on Doctor Who are a race of reptilian humanoids from Earth's past, making their first appearance in the show in 1970. Frank and Schmidt cite Inherit the Stars, a 1977 novel by J. P. Hogan as containing a similar hypothesis, but also say they were surprised by how rarely the concept was explored in science fiction.

The World Without Us is a 2007 non-fiction book about what would happen to the natural and built environment if humans suddenly disappeared, written by American journalist Alan Weisman and published by St. Martin's Thomas Dunne Books. [1] It is a book-length expansion of Weisman's own February 2005 Discover article "Earth Without People". [2]
The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
Imagine life with no humans. One group of researchers has done exactly that -- and they even made a map to show how the world might look sans homo sapiens. SEE ALSO: California drought may ...
Paleontologists are revealing early humans actually co-existed with a human-like species some 300,00 years ago. Early humans co-existed with human-like species some 300,000 years ago Skip to main ...
He noted "people deny the presence of intelligent beings on the planets of the universe" because "(i) if such beings exist they would have visited Earth, and (ii) if such civilizations existed then they would have given us some sign of their existence". This was not a paradox for others, who took this to imply the absence of extraterrestrial life.
If an earlier civilization existed on Earth millions of years ago, we might have trouble finding evidence of it -- but that doesn't mean it didn't exist.
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
