The formation looks like a bridge. In the movie, the people making it stand on the bridge and water only goes up to their waist.
The bible says it was a wall of water to the left and to the right. It doesn't look like wading to me. Like I said just wait, scientists will be shown the fools they are for these silly theories soon. I think science is great, I subscribe to scientific mags. But I would think any scientist that knows anything about dimensions and quantum mechanics can see that God isn't impossible and that there is much more to this universe than we can sense with our body's organs.
