No. That is a complete mistatement of the 2nd Law of Thermodynamics.
Specifically, it refers only to an *isolated* system ... one with no external energy source. Every living organism is not an isolated system (it gets energy from its environment). And the earth and all life on it is not an isolated system (it gets energy from the sun).
Let me give you a simple example that doesn't even involve life:
A snowflake is a complex object (a water crystal) that emerges from something simple (water molecules). How is this possible? Because a snowflake is not an isolated system, but is in contact with external energy from the environment.
If a snowflake can develop tremendous complexity from something simple and disorganized, then why can't life develop in the same way?
Sorry, but your question is quite easy to explain.

This argument derives from a misunderstanding of the Second Law. If it were valid, mineral crystals and snowflakes would also be impossible, because they, too, are complex structures that form spontaneously from disordered parts.
The Second Law actually states that the total entropy of a closed system (one that no energy or matter leaves or enters) cannot decrease. Entropy is a physical concept often casually described as disorder, but it differs significantly from the conversational use of the word.
More important, however, the Second Law permits parts of a system to decrease in entropy as long as other parts experience an offsetting increase. Thus, our planet as a whole can grow more complex because the sun pours heat and light onto it, and the greater entropy associated with the sun's nuclear fusion more than rebalances the scales. Simple organisms can fuel their rise toward complexity by consuming other forms of life and nonliving materials.

It would be correct if we lived in a closed system. But energy is being received from the Sun all the time, and is distributed via plants to the rest of the Earth's inhabitants. As it is consumed and released, the energy is going from higher to lower, just as it should.
If what you are saying is true, then pregnancy is a myth, because we have a single cell becoming many more cells, seemingly against the law of thermodynamics.

Thermodynamics (specifically, the Second Law, which is what you are asking about) only applies in a *closed* system - which is to say, a system where there is no energy being added.
The earth is *not* a closed system - we are constantly receiving energy from the sun.
If you regard the sun and earth as a single system - then the loss of energy by the sun, radiating most of its energy into space and *not* at the earth, more than offsets the tiny decrease in entropy on the earth by the growth of organisms.

These complexities are the eradication of order, for instance, in the organized single celled organism, the order is higher then the multicelled organisms which have to set in chaotic states such as the survival extinction and so on like predator prey and the theater of pressure

You're question has the answer in it- because of the trend towards disorder, organisms have had offspring that are different than the parent's generation, and when some of those offspring are better suited to survival they outcompete with others for resources and get to reproduce, allowing them to pass along their genetic information with their new traits. Along the way, a colony of differentiated cells each performing a different task could fill a new ecological niche and was able to thrive and reproduce.

As you are using the terms, life is an exception to the law. Life causes compounds to go from simple to complex, stable to unstable. Plants take in CO2, a stable compound, and release O2, a relatively unstable compound. In our own bodies, we take in simple compounds in our foods, break them into simpler compounds as we digest them, then build them up into the more complex compounds that make up our bodies.
Now that our question has been answered, do you agree that evolution is correct?

Simple, evolution is the ability to outcompete your rivals.
Everytime a predator develops a new skill or ability, it's prey will develop a defense to it to keep from becoming extinct.
It works the other way around too, As prey develops new abilities to elude being food, the predators will develop new ways of getting them to keep from starving.

you're not seeing the big picture. if order is happening in one part of a system, a greater amount of disorder is happening on another.
this has Been shown in equations, predicting what has Been observed in study after study after experiment after another study after 3 more experiments.
it is. and that's it.
