Mercury and her craters

I have covered this subject before, and I am floored at the way it keeps getting by the scientists at NASA. To the eyes of this pirate, the craters on Mercury seem way to different from the ones on our moon (Luna) and those on Mars. If you have ever melted down a bic lighter you would see what I am talking about. Rather than standard "impact" craters, I think the craters on Mercury are the result of bubbles. Pockets of gas and material that come to the surface, forced by the heat. Just one man's opinion that I think should be recognized before NASA comes out with "new findings on the formation of Mercury and the carters"
