The fun thing about biology is that if there can be something built by a true omniscient creator, then biology is the closest thing to it. All of reality and all of physics is used. It is simply what works no matter how arcane or difficult to understand the concept and mechanisms behind it is. Like all engineering projects there are still physical constrains of course but there is no limit on the technology allowed. There is simply no "cutting edge knowledge" or "unexplored science" to evolution. Literally everything can be applied within the physical constraints of a carbon-based lifeform
The way I like to think of it is that life, most broadly and abstractly conceived, falls like water through the space of possibilities afforded by nature, and there is no limit to how complex that "shape" can be (where "shape" is something in a space of possible combinations of forms, mechanisms, tools that are simultaneously used by one organism, a search space of possible combinations rather than a literal shape).
And whatever "intelligence" it would take to consciously think from first principles to those kinds of shapes, well, there's no upper limit to the possible sophistication that might be required to manually get there. But nature gets there blindly, and uses every possible thing.

Except having to work from a legacy codebase via incremental changes. No way for evolution to explore silicon based life when it kicked off with carbon.
