Or nuclear bombs. Why could we apply the same argument here? "We never see any nuclear explosions on earth, either during human history or in the form of radioactive craters, therefore it is very implausible that if we combine specially crafted and refined substances we will get something like that."

Natural nuclear fission did occur on Earth, though it didn't leave a crater.

And nuclear fusion is occurring naturally in the Sun and also not leaving craters. :)
