Here is a closer look at the real crater maker. Other kinds of rock form differently, some in goo, I have good examples. If you have time you can watch rocks grow. Let one of those ant nests grow by gravel and you can pick the flat rounds that you find over time and pinkish orange stones with black spots. Put them in a pile and take pictures as a comparison and see the changes. On this you get close enough to see the tube shapes form as if you grew a new arm from your hand and repeated that. Like the snake that came from space in Men in Black 2, Serleena. Add that to the game list. Next we can look at the white part of that picture that is the shape of the UFO I have showed with a chemtrail over Montana...Very interesting...
