It would have to be that way, because if the elements were to be put together in a planned, or predestined, or systematic way, there would need to be a force directing them. Charles Darwin advanced the theory of evolution by natural selection in1859. It is not scientific to guess at conclusions. In addition, whatever has been determined to be scientific fact always turns out to be part of an elaborate pattern. When you take a closer look at fact-based science, it is very systematic.
Science looks at the way something is.
Research may have to discover how it is. It is absolute, conclusive, and unalterable. The way you do a certain calculation, whether basic math or complex algebra, is the way it will always be done, and it will always produce the same result. The physical and life sciences are all very precise and systematic sciences. Each follows a specific pattern.
