Science ( Combination of Physics, Chemistry and BIOLOGY including Math). When, biology is brought in the picture, it directly relates to life and organisms.
Chemistry and physics were born when the universe started.Biology is new in the sense 14 billion history of universe. Life has started only 3-4 billion years ago according to recent statistics and discoveries of fossils and comparing history of earth. Rock from the moon to helped scientist to say earth and moon's age. Now, Sociology and religions of human beings are even more recent 100,000 yrs or even may be less.
Chemistry and biology seems closely related when it comes to life. A small chemical changes in an organism, will cause living being to become non living thing in a second. Hydrogen and oxygen are gases when they are seperate but as they come together they form water. Reaction to form new compound with given right temperature and pressure and other factors are also properties of matter ( don't ask why H and O makes water not alchohol). As oxygen and hydrogen combines with carbon, the whole chemistry changes and so does the properties of matter. When heat, pressure and temperature are right with all these chemical mixture, a new compound with new property develops which are not properties of each elements ( meaning boiling point, melting point, reactivity, pH of oxygen, hydrogen etc). Ignition of life from should have been from these chemical when they were primitive ( Not walking, talking like today) Meaning they were just chemical floating and reacting in pool of chemicals forming new compounds. Not even a cells are formed till this time ( Not one or two days but millions and may be billion years, our life is just 80 yrs on average now imagine 1 billion year which is not that fast). In this pool, a first or many proteins should have been formed. which were just complex molecule formed because of physical conditions. Famous Miller-Urey experiment proved it that GOD did not mixed it together. These protein's formed a chain polar/ non polar all kind of chemistry. Among these vast chains, some had property to replicate under suitable condition. Why replicate ? Like hydrogen attaches with another hydrogen to form hydrogen gas H2 or same with oxygen O2. Its must be chemical property of those combinations of carbon, hydrogen, nitrogen, phosphate to combine with similar compound. Now, dont get confused, its not making a new carbon out of no where, but it is just making same chemical partner just like as its property.
Now, from protein to RNA to DNA to virus, virus to plants, plants to animals. The journey of life started. Amazing !!! Remember, we are very complex animals but we are animals, no different than others but only with intellegence. A zygote acts like single celled bacteria, from single cell to 3 lbs baby. Unicellular bacterias are individual organisms just not related to each other. Cells are fundamental units of life. Our body are big COMPLEX colony of cells who are just trying to live or continue its reaction.
