Yeah. One person looks at a fossil of what he thinks is a tiny lizard and another person looks at the same fossil and claims it's the forerunner of humans.It just depends on what each person wants to see.
You are arguing from ignorance again. Just because we cannot prove to you that dinosaurs evolved into birds doesn't prove that it is impossible.
here is evidence that supports my claims;
The Lungs of Reptiles vs The Lungs of Birds;
THE SPECIAL LUNGS OF BIRDS
Birds have a very different anatomy from their alleged ancestors, the reptiles. Bird lungs operate in a completely different fashion from those of mammals. Mammals inhale and exhale air through the same windpipe. In birds, however, the air enters and exits through opposite ends. A special "design" such as this has been created to provide for the high volumes of air needed during flight. Evolution of such a structure from that of reptiles is not possible.
The respiratory system of mammals and birds operate on completely different principles, primarily because birds need oxygen in much greater quantities than do mammals. For example, a certain bird could require up to twenty times the amount of oxygen necessary for humans. Therefore, the lungs of mammals cannot provide oxygen in the quantities required by birds. This is why the lungs of birds are created upon a much different design.
In mammals, air flow is bidirectional: air travels through a network of channels, and stops at the small air sacs. Oxygen-carbon dioxide exchange takes place here. Used air follows a reverse course in leaving the lung and is discharged through the windpipe.
On contrary, in birds, air flow is unidirectional. New air comes in one end, and the used air goes out the other end. This provides an uninterrupted supply of oxygen for birds, which satisfies their need for high levels of energy. Michael Denton, an Australian biochemist and a well-known critic of Darwinism, explains the avian lung in this way:
In the case of birds, the major bronchi break down into tiny tubes which permeate the lung tissue. These so-called parabronchi eventually join up together again, forming a true circulatory system so that air flows in one direction through the lungs . Although air sacs occur in certain reptilian groups, the structure of the lung in birds and the overall functioning of the respiratory system is quite unique. No lung in any other vertebrate species is known which in any way approaches the avian system. Moreover, it is identical in all essential details in birds
In his book A Theory in Crisis, Michael Denton also points out to the impossibility of formation of such a perfect system through progressive evolution:
Unidirectional airflow in the bird's lungs is facilitated by a system of air-sacs. These sacs collect air and then pump it regularly into the lung. In this way, there is always fresh air in the lungs. A complex respiratory system such as this has been created to satisfy birds' needs for high quantities of oxygen.
Just how such an utterly different respiratory system could have evolved gradually from the standard vertebrate design is fantastically difficult to envisage, especially bearing in mind that the maintenance of respiratory function is absolutely vital to the life of an organism to the extent that the slightest malfunction leads to death within minutes. Just as the feather cannot function as an organ of flight until the hooks and barbules are coadapted to fit together perfectly, so the avian lung cannot function as an organ of respiration until the parabronchi system which permeates it and the air sac system which guarantees the parabronchi their air supply are both highly developed and able to function together in a perfectly integrated manner.
In short, the transition from mammal lung to avian lung is impossible due to the fact that the lung that would be in a transitional developmental stage would have no functionality. No creature without lungs can live for even a few minutes. Therefore, the creature simply would not have millions of years to wait for random mutations to save its life.
