Kook alert. You have been warned.
OK. Thank you. However, these particular "kooks" are "kooks" that continually make predictions before the fact that prove true when the evidence comes in... including predictions on the nature of comets composition made prior to the destructive testing of Deep impact whose results surprised its designers but did not surprise these "kooks".
Look at the picture above, Cogitator. Just exactly what are those spherical round objects littering the Martian landscape? How do they fit into Areology or Geology? NASA calls them "Blueberries" because of their bluish-gray coloring and round shape. NASA says they are a form of hematite. They literally are everywhere on Mars. These "kooks" have been able to duplicate the blueberries here on Earth in the lab using electrical discharge (humungous bolts of lightning). No one else has a viable theory of how they were created.
I suggest you look at their arguments and their evidence before you label them "kooks" and dismiss them out-of-hand. The test of any theory is how predictive it can be... and these guys are building quite a track record.
