Don!
Mars has a rich history that involves water. Get use to it. Swim in it. Grab a inner tube and go rafting.
My self, I think Mr. Dr. Malin is trying to say something with emphasis. You don't get that.
"smoking gun evidence" "smoking gun evidence" "smoking gun evidence"
does that help?

He's trying to say something here Don! don't turn your back on him.
Hey if he was able to communicate better he wouldn't be a geologist so give him a brake.
Persistent Water Flow; this is no joke when it comes to Mars. Stop trying to prevent the man from speaking, my-god!
I give him credit for saying what must be said; 'This people talking about a dry Mars are misinformed'.
Perhaps I taken up to much of your time? What do YOU think Dr. Malin means by "smoking gun".
