As you say... There is no such thing as a simple cell. Advances in microbiology have shown the incomprehensible complexity of the living cell. A few years ago, scientists decided to try simulate one of the smallest known genomes of any organism (525 gene). The scientists had "a cluster of 128 computers running for 9 to 10 hours to actually generate the data on the 25 categories of molecules that are involved in the cell's lifecycle processes."

Interestingly, the article unwittingly suggests an Intelligent Designer may be responsible... "Now figure that millions of bacteria could fit on the head of a pin and that many of them are an order of magnitude more complex than M. genitalium. Or ponder the idea that the human body is made up of 10 trillion (big, complex) human cells, plus about 90 or 100 trillion bacterial cells. That's about 100,000,000,000,000 cells in total.
Also... Re "simple cells"... Have you seen some of the animations done by Harvard university, or Oasis, or others of the 'manufacturing city' within a cell. They are awesome evidence of the Creator
