Oh how I wish I was born at least 20 yrs later ! Life on other planets would just confirm what I have always thought MUST be possible.Some of the scientists last night were not so young anymore and it must be a frustating for them to think that a life's work may not reach fruition in their lifetime.I did wonder if putting some instruments on our moon would not bring them any nearer,so to speak, to what they are seeking ?? Well I suppose I should be satisfied with the many advances that have occurred in my lifetime.Sad to say there are so many that I have NO idea how they work ! My 9 yr old grandson probably knows more than I do.
