Who needs the Sun and Water Anyway ?

Earthlings Do, they cannot exist without it.

The answer is that without the Sun, Earth's land, water, and air would all be frozen solid! Life on Earth would cease to exist. That's because almost all living things rely on the steady light and heat of the Sun. The Sun's heat makes liquid water on our planet possible

The sun is the closest star to Earth. Even at a distance of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit. It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth.

The sun, on the other hand, offers free and clean energy in abundance. In fact, it gives much more energy than we can ever possibly use. Perhaps, someday inhabitants of our earth will manage to take full advantage of it.

Without water, there would be no clouds to provide a buffer from the heating power of the sun. Without them the sun would pour down. Dry air would suck out whatever moisture it could find, wherever it could find it, and the noses and soft tissues of any being that lived would shrivel. There would be no sweet scents, since smells are conveyed by moisture.

The composition of the air would change too. All the methane currently stored in ice, bogs, and the ocean, would be released. That would reduce the balance of oxygen in the air, and increase the heating effect of the sun. The dust in the air would be blown hither and yon, with nothing to wash it down. Temperatures would swing from extreme to extreme, getting hotter as time went on.

Water in the air feeds the earth, and water in the earth feeds the air.

The hydrologic cycle works as follows: From it's most usable state, water evaporates and joins the air as water vapor. When the air cools, the vapor condenses and creates clouds, which help block heat from the sun. Colonies of the ice-nucleating bacterium blown into the clouds by wind, help them to precipitate and fall as rain, snow, or hail. Much of the precipitation is stored on land as groundwater.

Water is a life giver—even a life creator. It lies at the basis of our understanding of how life works. It also lies at the basis of how we understand our own personal lives. Of the four (or five) basic building blocks of life, water is the only one with a visible cycle, which we call the hydrologic cycle. Fire has no cycle that we can see, neither do earth or air. And we don't understand spirit enough to know if it does or not. Water is a constant reminder that life repeats.
