The two theories which have been very frequently debated are the theory of evolution and the theory of creationism or the theory of intelligent design. Those who support the Darwin’s theory of evolution give examples of the scientific excavations done and the different types of human skeleton found in these excavations. They say that the different forms of the human skull during the evolution clearly show how human form has changed while adapting to the surroundings. They are mostly those who don’t believe in God and look for a scientific reason behind everything (Scott-Phillips et al, 2011). On the other hand those who support the theory of creationism say that the human form is too perfect to be a product of evolution. It is too complex to have been evolved on its own. They argue that the complexity of human body and mind proves that it has been created by the almighty and has always been like this ever since the humans have been on earth.
