Romans 1 says that God has planted evidence of Himself throughout His creation so we are without excuse. In this essay we'll be looking at different types of evidence indicating that God really does exist.
A "Just Right" Universe
There's so much about the universe, and our world in particular, that we take for granted because it works so well. But Christian astronomer Dr. Hugh Ross has cited twenty-six different characteristics about the universe that enable it to sustain life. And there are thirty-three characteristics about our galaxy, our solar system, and the planet Earth that are finely-tuned to allow life to exist.{1} I do well to make the meat, potatoes, vegetables, and bread all come out at the same time for dinner; we're talking about fifty-nine different aspects all being kept in perfect balance so the universe hangs together and we can live in it!
Our Earth, for instance, is perfectly designed for life. It's the "just right" size for the atmosphere we need. Its size and corresponding gravity hold a thin, but not too thin, layer of gases to protect us and allow us to breathe. When astronaut John Glenn returned to space, one of the things that struck him was how thin and fragile our atmosphere is (only 50 miles above the Earth). If our planet were smaller it couldn't support an atmosphere, like on Mercury. If it were larger, like Jupiter, the atmosphere would contain free hydrogen, which is poison for us.{2} Earth is the only planet we know of that contains an atmosphere that can support human, animal, and plant life.
The Earth is also placed at a "just right" distance from the sun and the other planets in our solar system. If we were closer to the sun, we'd burn up. If we were farther away, we'd freeze. Because Earth's orbit is nearly circular, this slightly elliptical shape means that we enjoy a quite narrow range of temperatures, which is important to life. The speed of Earth's rotation on its axis, completing one turn every 24 hours, means that the sun warms the planet evenly. Compare our world to the moon, where there are incredible temperature variations because it lacks sufficient atmosphere or water to retain or deflect the sun's energy.
Speaking of the moon, it's important that there is only one moon, not two or three or none, and it's the "just right" size and distance from us. The moon's gravity impacts the movement of ocean currents, keeping the water from becoming stagnant.{3}
Water itself is an important part of a "just right" world. Plants, animals and human beings are mostly made of water, and we need it to live. One of the things that makes Earth unique is the abundance of water in a liquid state.
Water has surface tension. This means that water can move upward, against gravity, to bring liquid nutrients to the tops of the tallest plants.
Everything else in the world freezes from the bottom up, but water freezes from the top down. Everything else contracts when it freezes, but water expands. This means that in winter, ponds and rivers and lakes can freeze at the surface, but allow fish and other marine creatures to live down below.
The fact that we live on a "just right" planet in a "just right" universe is evidence that it all was created by a loving God.
