> 1. Fact ... Matter blocks light.

Good job, but xrays are light too. Xrays can pass through some matter and not
others.

> 2. Water is denser than air ... therefore more molecules per volume.

So is glass.

> 3. More molecules per volume ... more light blocked.

Glass has more molecules per volume than water or air, it's a solid.

So you're talking about visible light again?

Right, depending on the condition of the water.

What about glass? So by your theory Silicion dioxide should block even more light
(which it doesn't).

> 7. Less volume of water ... object and eye are closer together.

Depending on the medium that connects your eye to the water, if it's more airlike,
it'll be refracted more.

Depending on which light wave we're talking about, and also which eyes we're talking
about.
