If Humans Never Existed

This is an alternate timeline where humans never existed. Many species, such as mammoths and saber-toothed cats, would still die from global warming, while some, such as the Megalania and the Haast's eagle, would still exist.

Timeline
more coming soon...
 * 30,000 BC - Prehistoric Australian animals, such as short-faced kangaroos, marsupial lions, and the Megalania, would still be alive.
 * 10,000 BC - The ice age ends. However, even if humans never existed, many ice age animals, such as mammoths and saber-toothed cats, would still go extinct due to climate change.
