Water has been proven to show signs that respond to human emotions and or feelings !  , the ❄snowflakes /ice have been proven to show or display  beautiful patterns of perfection when a person is happy, kind and in a great mood!  When a person has been ugly, rude, or mean outwardly expressing negative feelin6gs towards the water when its frozen it lacks the beauty of semetry   order and beauty,and is shows or displays a sense of messiness . It lacks tge Beaty of it's typical organized structure, ir beautiful patterns we had seen , when it was treated with kindness love and care .  So I disagree with his opinion that  human beings would lack the ability to communicate with aliens or a higher intelligence. If we run into a situation  where we cannot  understand another being that's living. Being the humans beings we are , we want to be seen and heard, and we want to have a better understanding of the unknown.  We crave knowing and understanding the things we don't. Life will find a way.
