My point was to say that darwinian evolution is no more acceptable for an engineer since biochemistry describes irreductible complexity mecanisms, engines, pumps, codes, coders, decoders, machines etc... in life at the molecular level.

After that, anyone is free to conclude that we don't know where it comes from, or a designer did it, and who is this designer. But darwinian evolution is dead as a "science".

It’s not dead, it’s just that its applicability does not necessarily extend into biology at the molecular level.

Indeed. Darwinism is about evolution, and does not touch on Origin of Life - only what happened once Life had already been sparked into existence. A lot of people have mixed the two up, especially religiously because of failing to recognize that difference.

The reason phylogenetic trees can be so thorough is because evolution is real.

First God created life, then God continued to create life. Life evolved just the ways cars and airplanes have evolved -- in reaction to the environment and greater understanding. Once roads developed painted lines the cars could adapt to add painted-line-sensors, for instance.
