Water is the giver of life, so I start my search for sentience beyond, with Saturn, not Mars. The rings of saturn are swirling clouds of water ice. Tiny sparkling fragments, crystal balls, huge icebergs, that reflect the universe in empty silent space. And Saturn is surrounded by many watery moons, each one full of water ice.
Each borosilicate glass vessel contains melted water ice. This is a life-filled universe of watery saturn planets and their moons revolving around a centre, waiting for life to grow.
