Organic molecules discovered by NASA’s Curiosity Mars rover suggest the presence of alien life on Mars.
Scientists claim that organic molecules present in truffles, coal and oil on Earth have been identified found the Mars surface. These organic molecules are called Thiophenes. Their presence could be a sign of ancient life on the Red Planet.
Since thiophenes contain carbon and sulfur, that are the two main ingredients essential for life. Most probably source of these chemicals are the biological processes of primitive lifeforms. But their presence can also be result of some meteor impact too.
Washington State University astrobiologist and lead author Dirk Schulze-Makuch, said, “We identified several biological pathways for thiophenes that seem more likely than chemical ones, but we still need proof,”
However scientists are not yet coming to any conclusions.
Shulze-Makuch added, “If you find thiophenes on Earth, then you would think they are biological, but on Mars, of course, the bar to prove that has to be quite a bit higher,”
“As Carl Sagan said, “extraordinary claims require extraordinary evidence”
Schulze-Makuch said, “I think the proof will really require that we actually send people there, and an astronaut looks through a microscope and sees a moving microbe.”
