(cont'd from yesterday's post)
- Life requires minerals that are bound in our planet's rock. In the course of earth's water cycle, those minerals are dissolved and distributed all over the world. Water dissolves without destroying lots of things we need, while not dissolving necessary things.
- Water's heat capacity helps us stay temperature-stable within a narrow range.
- Normally the frozen state of a liquid would contract and get denser. If frozen water got denser, it would sink. Lakes and rivers would be frozen from top to bottom, killing all aquatic life. But floating ice actually insulates and preserves the liquid state of the water beneath it.
"Water is the driving force of all nature," said Leonardo DaVinci. He didn't know what the last several hundred of years of science has discovered, but his intuition was correct.
The fine-tuning of water, and of nature in general, make possible the existence of complex beings such as ourselves, according to Michael Denton.
