OP, if you look at the US dollar bill, you will see a circle border surrounding the pyramid and the bald eagle. If you look closer, you will see flood waves surrounding the circle borders.

At the far side of each circle we see what appears to be an enormous splash causing the waves, and at the centre of the splash we see what appears to be a worm or snake's tail, which is causing the splash and the tsunami waves.

I believe that this circle represents the earth. the waves represent the flood, and the serpent / dragon tail represents satan being imprisoned at the pole.

Google the US dollar bill and check it out in high resolution and you'll see what I'm talking about. It is very clear.
