My contention is that due to the increasingly complex steps involved, the process was more likely to have been intentionally guided rather than driven by the unintended consequences of random events.
1 - what evidence do you have that any of the steps was particularly more complex than any other?
2 - if you want to hypothesise a guide to evolution, fine, but you need to find evidence to support your hypothesis.
3 - even if you somehow demonstrate that the current understanding is somehow limited or incorrect, all that does is revert us to 'we don't know', it's not a validation of your god hypothesis.
You've suggested 'increasing complexity' but you've given no reason for anyone to think that this understanding is correct. Thy system, over all, could be considered to be more complex, but each individual step on that pathway might well have been relatively minor - indeed, it's almost certain that there were steps which reduced complexity, either over all or within particular organisms or subsystems.
