Regardless of whether or not God created Adam and Eve or whether or not you evolved from lower life forms, that particular Thermodynamics argument that keeps getting repeated does not apply.
Why?
Because the Laws of Thermodynamics apply to CLOSED systems.
What the heck is a "closed" system?
It is a system that is totally isolated from the rest of the universe with nothing coming into or out of the system.
Two rats in a box that is hermetically sealed and perfectly insulated and in total darkness would be an example of a closed system.
After a million years, those two rats would have died of starvation and totally disintegrated into atoms. Disorder (entropy) would have increased.
The Earth, however, is NOT A CLOSED SYSTEM.
Every day, the Earth is bombarded with a immense amount of solar energy.
It takes energy to make order out of disorder and the Sun provides that energy to the Earth.
With solar energy, plants take carbon dioxide and turn it into complex sugars and starches by the process of photosynthesis.
Animals consume several times their body weight of such food (energy sources) throughout their lives to make themselves more complex.
Over a million years, those two rats released into a virgin forest with solar energy will have produced billions of tons of rat progeny over the centuries.
However, that solar energy comes at an entropy cost at it's source.
The Sun can produce that solar energy only by consuming 4 million metric tons of matter every second.
In other words, the "Entropy Price" that the Laws of Thermodynamics demands to keep you "organized" is paid for by the Sun.
The price to keep you "organized and complex" has also been paid by carcasses of the hundreds of chickens, pigs, cows and fish and the hundreds of bushels of fruits, grains and other plant life that you have eaten an "disorganized" through your life. They were the "delivery vehicles" that brought you what was left over of the original amount solar energy left after they tranformed it into the type of energy (sugars, fats, proteins, etc.) that your body can use and after they took their share.
Once you die and you can no longer take in energy, you will then no longer be able to keep entropy at bay and maintain your complexity. You then will succumb to the disorganization of Entropy.
Dust to dust.
Until then, enjoy your complexity.
Remember who paid the Entropy Price for it.
