nothing, nothing, nothing...big bang?

2) Basic bacteria *today* have complex DNA. This is not true of the bacteria in the past. Complexity increases the more organisms evolve. The first living organisms were self-replicating cells that were most likely composed of RNA (the precursor to DNA). As for how they got there, you'd have to read up on abiogenesis, but it involves the early Earth environment being in the right state for life, and a spark of energy (possibly lightning) that formed the first chemical reactions that led to self-replicating organic material.

To my understanding they have never created RNA in a lab before, or a functioning cell. I guess its hard trying to play God?

That doesn't mean it couldn't have happened by itself.
