The origin of life

Abstract

For many centuries scientists have been debating the question of how life on earth originated. With the increase in knowledge and technology in the twentieth century, realistic explanations are around with regard to the nature of life and its origin. One thought is that life has always existed, while a thought which is discussed deals with life originating as a slow and natural process following the big bang. Long after the big bang primitive earth formed, followed by the formation of prebiotic organic compounds. As these compounds became more concentrated they reacted spontaneously into elementary precursors of life such as amino acids and proteins.
