It could only be sheepbirds... Jeez am I the only smart one here?

The only thing a flock could be is sheep or birds, otherwise they would have said herd or another name for a group of animals.

The story stats these kids became lost from the home territory while attending their father's flock. Flock of what? Surely someone asked this question. Surely it would be a clue as to where these kids came from. And where was the boy buried? Loads of questions.

Your comment has elements of truth to it, but they're twisted and distorted. We don't live in a one-dimensional universe, but a four-dimensional one: up/down, left/right, forward/backward, and time. As for where we go after death, we could be here long enough to find out if we decided to argue about it. As for visitors from space moving through a dimensional field, that I can't even make sense of.

Here's where I'm coming from:

It has been postulated that our universe was originally eleven-dimensional, a tiny 11D bubble in a substance known as quantum foam, which is supposedly the underpinning of reality (the eleven dimensions account for the eleven needed to make the math of string theory work out). This quantum foam is, for all intents and purposes, randomness.

For some odd reason, that bubble that would become our universe began to swell to unimaginable proportions, though it was still infinitesimal on our scale. As the bubble grew exponentially, it split off from the sea of quantum foam, and six of the eleven dimensions shrunk back down to quantum scale. The remaining four, the ones I've previously mentioned, continued to expand into the Big Bang and the universe we know.

Consider, for a moment, the implications an extra special dimension would have on the anatomy of the children should they come from, as you claim, a "higher dimension".

Picture a 2D world, where the people are basic geometric shapes: squares, triangles, pentagons, and the like. This 2D world is flat. It's like a piece of paper. The people in it have to concept of "up", because they cannot grasp a third dimension.

Now, imagine that piece of paper with a human being standing on it. The paper begins rising, passing through the person as it does. What would that person look like? A couple of strange, pulsing ovals of rubber, then cloth or leather, then, when the piece of paper gets to the jeans, the ovals become very rough circles. Eventually the two circles of our legs join up and create an oval perpendicular to our feet: our waist. Around this time, a collection of smaller circles (our fingers, then eventually hand) appear out of nowhere and shift and pulse as the paper rises. Finally, our arms meet our torso at the shoulders, then the oval shrinks to another circle, our neck, before expanding again and pulsing all kinds of different shapes and materials when it comes to our faces. Finally, an extremely spiny circle coalesces out of the weirdness of our faces, and gradually shrinks away to nothing.

This is how a three-spatial-dimensional human being would look to a two-special-dimensional sentient triangle. A series of pulsating, rapidly shifting blobs. That's how a creature from a four-special-dimensional universe would look to us: a collection of rapidly shifting and pulsating orbs of various changing materials. Eyes would appear out of nowhere, along with portions of fingers and pieces of clothing.

A universe of a different dimension would have completely different rules for its reality. There is no chance whatsoever that a higher-dimensional being would look like a human to us.

If you're not talking about spatial dimensions, but alternate realities, some of the same rules would apply. If our universe has an edge, and we could cross it into another one, the laws of reality would be drastically different from those in our own.

On the other hand, if you're talking about worlds like most people would talk about planets, and space to you is a "dimensional field", then your points are valid.

The odds are as close to zero as you can get that living creatures from another universe or dimension would look almost exactly like us.

The article author's guess about the children being Flemish, suffering from a form of malnutrition, and wandering in a cave or forest is the likeliest explanation.

It is an ancient belief that rock is a barrier between dimensions or other worlds. I am an avid spelunker; every time I enter a cave I wonder if I will later emerge into the world I just left, or something entirely different and strange....
