What's the lamest defence of Theism you've ever heard?

It's not perfect (it literally couldn't be) but the design is pretty apparent when you look at how the cell works.

Only if you think argument from analogy and complexity are compelling.

Problem is, complexity is not a sign of design.

It's not just complex, though. There are so many purposeful interactions that need to take place in order for the cell to regulate itself. These interactions are dependent on intricate structures, which are dependent on sequence of characters in DNA. When you remove one enzyme, the whole system might no longer be able to function. So the problem is that in order for it to work well enough to evolve (reproduce), you need tens of thousands of nucleotides in a proper sequence. It couldn't get there gradually, at least not by mutation and natural selection.
