Then show us the scientific methodology, unit of measure, and statistical tests use to detect design.
The scientific methodology for determining the workings of minute organisms and systems has increased the knowledge and understanding of them. We can now observe the inner life of the cell. We now know that there are 250 molecular machines in Yeast alone! Not only can we know of these machines we can look deeper and see the molecular machines themselves and with scientific experiments learn how they work. Before 1950 a cell pretty much was still thought of as a blob of gel like substance.
We can do experiments to test these molecular machines now that can show how they work and how by taking away parts in knock out experiments and mutational sensitivity tests. The multitude of these elements of life give future experiments plenty of opportunities for learning.
The functions and forms of these machines are all tested and documented for design elements like those found in human design. There are motors, pulleys, assembly lines, messengers, switches and even highways that cargo is carried. There are even molecular rafts that carry loads.
According to the journal Accounts of Chemical Research, a molecular machine is "an assemblage of parts that transmit forces, motion, or energy from one to another in a predetermined manner.

Annual Review of Biomedical Engineering wrote that "these machines are generally more efficient than their macroscale counterparts,"

"The entire cell can be viewed as a factory that contains an elaborate network of interlocking assembly lines, each of which is composed of a set of large protein machines. . . . Why do we call the large protein assemblies that underlie cell function protein machines? Precisely because, like machines invented by humans to deal efficiently with the macroscopic world, these protein assemblies contain highly coordinated moving parts."
Evolution doesn't predict such orderly precise and purposeful machine like design, machines designed by humans. We see actual molecular machines performing just like human created machines (but far more advanced) we observe their function and purpose and the manner in which they are designed which confirms they are designed in the same way as humans design. That is the evidence, that is how we tested and confirmed the existence of molecular machines and experiments tell us how they work and show engineering in their makeup.
