There is as much water per square mile on Mars as there is on the continents of our home world. - Robert Zubrin

The evidence from our orbital images shows that there was liquid water on the surface of Mars for about a billion years of the planet's early history, a span roughly ten times as long as it took for life to appear in the Earth's fossil record after there was liquid water here.

While disputes about overpopulation, racial equality, pesticides, resource limits, nuclear power, biotechnology, and global warming may appear to be about different subjects, they are ultimately but different faces of the same conflict: a fundamental debate over the worth of humankind.

If the human mind can understand the universe, it means the human mind is fundamentally of the same order as the divine mind. If the human mind is of the same order as the divine mind, then everything that appeared rational to God as he constructed the universe, it's "geometry," can also be made to appear rational to the human understanding, and so if we search and think hard enough, we can find a rational explanation and underpinning for everything. This is the fundamental proposition of science.
