The thing about rocks on the beach spelling something out is that we immediately know the source because we're very familiar with that source. We know that humans do that sort of thing. That's why we don't think the ocean just washed them up that way.
What someone is saying when they say rocks spelling out letters on the sand, which is what alerts us to its artificiality, means that other things we find in nature that don't share the properties of the order of the rocks, actually DO share the order of the rocks. The sand is as artificial as the rock message that is distinguished from the sand by its artificiality, because if the rock message is artificial, the sand non-message must be too.
In other words, they are babbling incoherently.
