Life on Earth requires a lot of “fine tuning.” Our planet is just the right distance from the Sun to allow freezing and melting, and the planetary axis tilted just so for seasons. There is a moon for tides to circulate and cleanse shores and oceans, an atmosphere to distribute heat (otherwise the sun-side would cook as the night-side froze), and a magnetic field that contributes to our protection from harmful solar radiation.

That all these needs were met (and many more) is all a big (coincidence) for evolutionists – we just lucked out and got just what we needed.

But we didn’t need rainbows. And yet, as astronomer Guillermo Gonzalez recently noted, we’re on the only planet in the Solar System to get them. What’s needed for a rainbow is:

Suspended water droplets in the atmosphere and the direct sunlight that results from the sun being between the horizon and 42 degrees altitude. This typically occurs just after a thunderstorm has passed and small droplets are still in the atmosphere, and the sky is clearing in front of the sun. Seems like a simple setup. This must be a common phenomenon in the cosmos, right?

But it isn’t so simple. Our moon doesn’t have the atmosphere. Mars doesn’t have the moisture. Venus has too thick an atmosphere and as we head further out, the other planets don’t have liquid water. So, the only planet to have rainbows is the only one with people on it to see them. To evolutionists that’s just one more (coincidence). To God’s people, just another example of his love and care. It’s as if someone has been trying to get our attention with a pretty shiny object writ large across the sky, saying, “Look here. ... This is important!” “I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth” (Gen. 9:13).
