Start Watching If We Had No Moon 
Without the moon, humans wouldn’t exist. Life, if it had started at all, would be in the earliest stages of evolution. Days would last four hours, winds would blow at hurricane force and there would be a dense and toxic atmosphere resembling that of Venus. Luckily, 50 million years after the formation of the solar system, our proto-planet was hit by a celestial body more than twice the size of Mars, which formed the moon. In this one-hour special, viewers will learn what Earth was like before the moon and what Earth would be like if the moon disappeared.
