Inside NASA’s Hidden Files

Despite the harsh weather conditions and extreme temperatures, scientists have long speculated that years ago, life existed on Venus. Evidence was mounting that Venus, often referred to as Earth’s twin, was once alive with oceans and forests and fluffy white clouds floating in an atmosphere of oxygen and nitrogen—until, little by little, the greenhouse effect warmed the planet and destroyed every aspect of life.

To confirm this scientific hypothesis, NASA sent a space rover to Venus to dig underground and transmit pictures back to Earth. The photos showed millions of bones and teeth. And they were all human.
