Pebbles In The Sky

Just a picture of some dusty old outcrops .... a few river pebbles stuck together in that sort of baked mud concrete you see anywhere there has been an old riverbed .....

Ancient Mars River Bed

But actually, this is Mars, and this proves that once there really was running surface water on Mars ..... and where there's water and sunlight, then on Earth there has been some sort of life (even the battery acidic streams near vents and volcanoes teem with bacterial life on Earth).

Maybe, just maybe, we are going to find the evidence that at least once ... we were not alone.
