Answer:

No, it doesn’t.

Step-by-step explanation:

The second law of thermodynamics states that in a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems increases. Equivalently, machines that spontaneously convert thermal energy into mechanical work are impossible.

If you combine milk and coffee, the entropy will rise until the mixture is entirely homogenous and you can no longer differentiate between the two substances. At that point, the mixture will be a single, dull hue.

But in the process of mixing up coffee, before it’s fully mixed together but after you have started mixing, you might notice some complex swirl patterns appear for a brief moment in the chaos before vanishing away.

That’s what human life is.

We’re not violating thermodynamics because if you take the system as a whole, including the sun and the earth, entropy is still increasing. The sun will eventually run out of fuel and die out. Eventually all suns will die out and the whole universe will be homogeneous and we will have heat death as the expanding universe rips complex atoms apart.

But there can be brief pockets of complexity within that system, that exists for a brief period of time, before eventually and inevitably fading away. It does not violate thermodynamics because entropy is still increasing in the system as a whole.
