We can't walk on water because it isn't solid. It's a liquid, and liquids won't "hold things up" like solids.
If we put pressure on a portion of the surface of the liquid, the molecules will just "get out of the way" of the thing applying pressure. This will allow the thing to just "go down into" the water. If you step onto the surface of the (liquid) water in a swimming pool, you'll sink.

No, it is not possible to see a mole of water (6.022 x 10^23 molecules) with the naked eye due to their extremely small size. A mole of water would consist of trillions of water molecules, far beyond what can be seen without the aid of a microscope.
Certain bugs, such as water striders, have long hydrophobic hairs on their legs that create a waterproof layer. This allows them to distribute their weight and take advantage of surface tension to walk on water without sinking. Their light body weight and leg shape also aid in staying afloat on the water's surface.
That was Franklin Delano Roosevelt.
