We know the exact age of Universe and the earth. We know when life began on earth. Is the formation of life a result of random grouping of atoms and molecules? Is evolution the outcome of random mutations? If so, is the chances of such series of random mutations resulting in formation of human beings, consistent with probability theories that it might be possible in some 4.5 billion years. My motto is "I doubt that although Human Evolution may be outcome of random events and hence a happening of chance, we could appreciate it for a rare outcome." But since I know almost nothing on this subject, feel free to teach me the basics.
