I'm over six hours drive from civilization. Temperatures here regularly reach 100 degrees Fahrenheit, but there's less than half an inch of rainfall each year.

 

Ah,the whole things are moving. It's like walking on water.

 

Yet, hidden amongst these dry dunes are clues that point to the dramatic influence the planet has had on human lives.

I've come here because although you’ll never know it, the story of this place is all about water. The clues are etched into that rock face there. Prehistoric rock outdating about 6,000 years in the pattern of the almost unlikely characteristics you've ever seen.

 

Whoa, what is that? Is it a giraffe? It's a giraffe. Look at that, here is a neck, here is its ear. Look at that, it's an eye, isn't it? That's really natural, isn't it? And that looks like a giraffe, dipping its head/ and drinking some water. We've got a herd of giraffes here. 

 

Looks like two cats. They are fighting. That, what is that? Looks like a figure of, a figure of a man who’s wearing a burqa. And that's clearly a crocodile which is especially odd here, that's an aquatic animal. It doesn't just paddle around. It needs a lot of water to live in. I find all the creatures that are depicted on these rocks are not desert animals. They need wet conditions.

 

In such a parched wilderness, how can this be? The only explanation is that 6,000 years ago, this place was wet. Once you know what to look for, the evidence is all around.
