Jan's faith that God created life on earth, not evolution, over rules well established facts.
For example earth is 4.6 billion years old and the first life forms for at least a billion years were anaerobic as there was no oxygen in the atmosphere until green plants began making it, less than 1 billion years ago:

In the late Proterozoic, oxygen levels in the oceans and atmosphere increased dramatically. By 600 million years ago, the oxygen in the atmosphere reached about one-fifth of today’s level (21 percent). The oxygen boom favored the evolution of lifeforms that could use oxygen to create energy. For other organisms, oxygen was poisonous, and they were forced into extreme airless habitats or into extinction. ...
Until about 430 million years ago, most aerobic organisms lived in the ocean and used oxygen dissolved in seawater. Then about 430 million years ago, life on land appeared. Small plants and invertebrates (animals without backbones) evolved the ability to live on land and use oxygen directly from the atmosphere. During the Devonian Period, 416-397 million years ago, plants evolved, as did the first four-footed animals.
This is from part 5 of the Smithsonian's Museum of Natural History's eight part series.
BTW, those "extreme airless habitats" are the guts of animals, man included, where they help break down complex foods, like starches, into simple sugars that man and other animals can use for energy.
If you want facts, instead of faith based opinions, on how life evolved on Earth, read all 8 in this series.
Here is small part from section 4:
"Life and Earth’s atmosphere evolved together. Over time, tiny photosynthetic organisms produced enough oxygen to react with the methane in the atmosphere, transforming it forever. About two billion years ago, the methane haze cleared and the sky turned blue."
As the solar out put ~ 4 billion years ago was only about 70% of what it is today, that powerfull green house gas, methane, CH4, as the atmosphere is the only reason there could be liquid water on Earth.
A huge number of various versions of trilobites were among the first land animals. So many trilobite fossil have been found that buying a few, as I have, is cheap. They did not need as much oxygen as the later four legged animals did as they moved very slowly.
