If we’re talking about creationism now instead of Catholicism, consider the order of creation established in Genesis:
Creation Day 1.
Watery, formless planet Earth suspended in the darkness and the void of space (no sun or any other stars, no moon, no planets yet existed—except for Earth).
Separation of light from the darkness—and the first indication that the planet is rotating (day and night cycle produced).
Creation Day 2.
Formation of Earth’s atmosphere, separating the water into two parts:
(a) oceanic and subterranean water
(b) atmospheric water.
Creation Day 3.
Dry land and oceans.
System to water the entire land surface using subterranean waters (involving springs or mist, or both).
Vegetation, seed-bearing plants, trees that bear fruit.
Garden of Eden (probably).
Creation Day 4.
Moon—complete with established orbit so as to mark passage of time (months, seasons, and years).
Stars and other planets.
Let’s stop there. Note the sun is created on day 4. This presents many problems.
- The temperature in space absent radiation from the sun is about 455 degrees below 0.
- Day 1 would involve an earth sized ball of ice. Not a watery planet.
- Light is created on day 1. Without a sun to provide it, where did that light come from?
- With no sun as a reference, how did the first day end regardless of if the planet was rotating?
- Day 2, forming the atmosphere. Still no sun, no heat, the planet is still an icy ball.
- Day 3. Oceans formed, Still minus 455 degrees the ocean would be ice from top to bottom.
- Plants created, Still -455 degrees, they all would die of cold.
- Day 4, now the sun is formed. Oceans still ice (it would take more than a day to thaw) and the plants still frozen and dead. The garden of Eden would be a barren frozen wasteland full of dead plant-cicles.
