New studies strongly suggest Mars was once covered in vast oceans

Could intelligent life have possibly evolved as it did here on earth? We know that life started quite early in earth's history.
NASA's Opportunity rover spent a full year around the outer edge in early 2007 and a full year inside the crater for close-up imaging. It entered into the crater in Nov 2007 and exited in Aug 2008. Unfortunately Opportunity was not in the vicinity of Cape St. Vincent (1/4 mi away) to do any close-up imaging as it did at Cape Verde, Duck Bay, Cabo Frio section.

We're left to wonder what any close-up image would reveal.
