Carl Sagan once said, “Extraordinary claims require extraordinary evidence.”

An international team of astrobiologists has found what they think could be a sign that ancient life existed on the red planet.  

Several organic molecules were recently discovered by NASA’s Curiosity rover including “thiophenes,” which are special compounds found in coal, crude oil, and white truffles back on Earth. 

Thiophenes are made up of carbon and sulfur, which means it is very possible that they could have been created during meteor impacts. However, the team has identified “several biological pathways that seem more likely than chemical ones.”

In other words, they are leaning towards the notion that there was once biological life on Mars. 

We still lack the “extraordinary evidence” as concrete proof, but this find is a massive step forward in the search for evidence of extraterrestrial life. 

The next step is to get a team of scientists up there. We’re looking at you, Elon…
