Clues to spotting life on Mars are right here on Earth

"Roughly 3.5 billion years ago, a blue-green algae known as cyanobacteria triumphed as the dominant form of life on Earth. It was also the first living organism large enough to be seen with the unaided human eye. One of the few places where this organism's fossils (called stromatolites) can be found is in the Pilbara, a dry swath of Western Australia that's considered to be the oldest place on Earth."

My notes. The theme of life on Mars keeps being repeated, over, and over again. Now we may have clues from looking at stromatolites here on Earth as to what Mars will show earthlings about life there, in the present or past.

Good news for life: Mars rivers flowed for long stretches long ago,


The oft repeated theme of life on Mars will have to be demonstrated as factual in science, otherwise it looks like a belief system repeated over and over to the public who pays the bills for all of this *science*.
