Well, you should know what I'm going to say next then.
You say god can do anything. Well what about the stories of Zeus transforming into a swan and raping human women? What about the Norse frost giant Ymir dying, crawling with maggots, and the maggots eventually became dwarves? Why are Biblical stories more plausible than stories in other religions? (Answer: They aren't.) If you say that the Bible stories are true, you don't have much choice but to believe crazy stories in other religions. They're both equally true.
And if you're going to say that transforming into salt must be interpreted, then you can't know what in the Bible must be interpreted and what must not. (On a side note: Arguments over Biblical interpretation have led to wars in Europe.)
