A sample obtained by NASA’s Perseverance rover of reddish rock formed billions of years ago from sediment on the bottom of a lake contains potential signs of ancient microbial life on Mars, according to scientists, though the minerals spotted in the sample also can form through nonbiological processes.
The discovery by the six-wheeled rover in Jezero Crater represents one of the best pieces of evidence to date about the possibility that Earth’s planetary neighbor once harbored life.
I had a friend that was 100% convinced that we have already found extraterrestrial life, and that it was already normalized. She was actually surprised when I have to explain that we haven’t found any evidence whatsoever of any living organism that had not originated on earth. She didn’t even believed me at first, she just thought I was misinformed.
I blame headlines like this.
