Man has resorted to research and inquiry to find an answer to the "curiosities" that are projected as a solution to the evolution of humanity. Science has been considered as a set of knowledge and activities that seek to achieve a "something" that arises from the need to face the challenges posed by the reality of coping and meeting needs, that is, what produces the deep knowledge.
With this it is understood that science is the necessary fact for the evolutionary existence of humanity, understanding that it can be latent or unconscious. It could be said that science was born in the first civilizations as for example in ancient Greece, being with these transmitters and at the same time recipients of knowledge of cultures. And with that, looking for natural and material explanations of the whole world.
Science has built the world and globalization, since it has been released several areas such as biology, cosmology, chemistry, physics, among many others. The parents of science promoted the transformation of humanity with their ideologies that humanity could not stop, an example of them is Pythagoras who seeks a separation between intellectual and practical activity (which was easy to capture due to the observation of the slave models of his time, completely neglecting technology).
Man advanced in different periods, bringing with him higher studies of traditional science at such a moment, in which centuries like the twentieth the discoveries or rediscovery of the sciences have provoked a totalizing and integrating eagerness of the different scientific branches, achieving a connection in man and the cosmos itself. Instructing the whole man to do the greatest work of transforming the earth and therefore helping the progress of humanity.
Let's conclude with this ... science is complex and deep that requires man for its application, likewise man requires it for his daily life, because if you visualize the environment everything has been the product of a scientific discovery.
