Imagine finding a planet where robots are programmed so that they can make other robots just like themselves from raw materials.

Now, imagine an alien scientist visitor coming to the planet and, after many years of studying these robots, the alien scientist visitor comes to the conclusion that since science can explain how these robots work, operate, function, and reproduce there's no reason to believe that there was an ultimate intelligent designer behind them.
The analogy above certainly is not perfect but it is sufficient to reveal the fallacious thinking of those who attack intelligent design behind life and the universe.
Of course, once there is a complete and living cell then the genetic progam and higly complex biological mechanisms exist to direct the formation of more cells. The question is how could life or the cell come into existence naturally when there was no directing mechanism in Nature.
Chance physical processes can produce some level of order but it is not rational to believe that the highest levels of order in life and the universe are by chance. For example, amino acids have been shown to be able to come into existence by chance but not more complex molecules or structures such as proteins which require that the various amino acids be in a precise sequence, just like the letters in a sentence. If they're not in the right sequence the protein molecules will not function. A single cell alone has millions of protein molecules!
There is no innate chemical tendency for the various amino acids to bond with one another in a sequence. Any one amino acid can just as easily bond with any other. The only reason at all for why the various amino acids bond with one another in a precise sequence in the cells of our bodies is because they're directed to do so by an already existing sequence of molecules in our genetic code. Without being in a proper sequence protein molecules will not function.
The sequence of molecules in DNA (the genetic code) determines the sequence of molecules in proteins. Furthermore, without DNA there cannot be RNA, and without RNA there cannot be DNA. And without either DNA or RNA there cannot be proteins, and without proteins there cannot be DNA or RNA. They're all mutually dependent upon each other for existence!
If the cell had evolved it would have had to be all at once. A partially evolved cell cannot wait millions of years to become complete because it would be highly unstable and quickly disintegrate in the open environment, especially without the protection of a complete and fully functioning cell membrane.
