This is an example of how we must be pretty careful when drawing firm conclusions in science as things are not always the way they initially appear to be. It was initially a perfectly reasonable hypothesis that those structures were man made as they did look like familiar man made structures.
Not only is there now an explanation of how these structures may have formed naturally, they are now known to have formed in the Pliocene era, well before there existed people thus completely ruling out them being man made.
