Written across a wall of the cave were the following symbols:

  
It was considered a unique find and the writings were said to be at least  3000 years old! 

The piece of stone was removed, brought to the  museum, and archaeologists from around the world came to study  the ancient symbols. 

They held a huge meeting after months of  conferences to discuss the meaning of the markings. 

The  President of the society, who also happened to be a Greens senator,  pointed to first drawing and said: 

  
"This is a  woman. We can see these people held women in high esteem.  
You can  also tell they were intelligent, as the next symbol is a donkey, 
so they were smart enough to have animals help them till the soil. 

  
The next  drawing is a shovel, which means they had tools to help them." 

  
Even further proof of their high intelligence is the fish which means

that if a famine hit the earth and food didn't grow, they seek food from the sea. 

  
The last  symbol appears to be the Star of David which means

they were evidently Hebrews."
The audience applauded enthusiastically.
Then a little old Jewish man stood up in the crowd  and said, 

  

"Idiots... Hebrew is read from right to left... It says:

'Holy Mackerel, Dig the Ass on  that Chick!'"
