Are we all Martians?

In this episode of Stuff You Should Know, Josh and Chuck dive into the fascinating scientific theory called panspermia - the idea that life on Earth might have actually originated from Mars or elsewhere in the cosmos. They explore how meteorites could potentially carry living microorganisms between planets, examining real evidence from Martian rocks found on Earth and incredible experiments showing bacteria can survive the harsh journey through space. It's a mind-bending look at whether we might all be descendants of ancient Martian microbes that hitched a ride on space rocks billions of years ago.
