You must have seen the name of a building spelt out in flowers on the ground in front of it. Looking down at them or from far away, you can immediately make out the name of the building or company concerned. That is a sign that the flowers are not there by chance, that they have been set out by gardeners and landscape designers. You may not see the gardeners actually doing it, but you can see that it has happened from the name the flowers spell out.
Alternatively, let us imagine that you leave the tiles scattered about at random on the table after a game of Scrabble. When you return, you see that the tiles now spell out the words: "I have won," and you immediately realize that someone has arranged them in a meaningful sequence. You would never imagine that they had come together by chance and formed those words, in just the same way that you would never imagine the name the flowers spelt out had appeared by chance. In short, if there is a design directed to a particular end somewhere, then you know that there must definitely be a designer behind it. You may not have seen the designer, yet you can be certain of his existence and intention from his work or the traces he leaves behind him.
The main idea we would like to convey with these examples is this: If there is even the slightest sign of something planned somewhere, there certainly lie the traces of a possessor of wisdom. For example, if you roll white stones down a mountain trillions of times, you will never see that they come to spell out the name of a building. If there is a word or a sentence somewhere, everyone will agree that that word or sentence must have been written by someone. Words without writers, or designs without designers are quite impossible.
The human body, on the other hand, possesses a structure trillions of times more complex than the name of a building or the words "I have won," and it is again totally impossible to imagine that this complexity could have come about of its own accord, or by chance. Moreover, the trillions of DNA that billions of living things have possessed for millions of years have been used in the most intelligent manner, written in the most perfect manner with no flaws, and placed in a tiny area invisible to the naked eye. That being the case, there is a Creator who planned and designed the cell and the DNA inside it so perfectly. Claiming the opposite means to go beyond the bounds of reason and attack the very foundations of truth, reason and logic.
Nevertheless, many people, who would readily say that it is impossible for letters to arrange themselves to form even three little words, can listen without objection to the deceit that it was all as a result of "coincidences" that billions of atoms came together one by one in a planned sequence and formed a molecule such as DNA, which performs such a super-complex task. This is just like a hypnotized person's submitting to the hypnotist and accepting by suggestion that he is a door, a tree or a lizard…
Flawless design samples in DNA are not limited to the above-mentioned examples. The coding of the data in DNA has been designed in a much more fascinating and amazing way.
