Ah, maybe I wasn't quite clear enough on what I meant about the first Day in Genesis. The ancients regarded a day more in terms of sunrises and sunsets than in 24-hour increments. And who wrote the Bible? The ancients. Forgive the Stargate: Atlantis reference.
Also, in Genesis light is created before the sun or the moon. So if the ancients regarded a day as being from sunrise to sunset and there was no sun to rise or set on the world at this time then what was this first "Day"?
Your definition of complex is dissimilar to mine.
The best way to explain the difference between evolution and adaptation through natural selection is the difference between mutation and genetic recombination. What evolution requires is added genetic information that is beneficially mutated - not a recombination of the current genetic information.
Genetic information can be copied and thus added, but its efficiency is also lessened. Increased genetic information may, as a whole, provide an added bonus to a previously performed task but at a lesser level of efficiency, and I don't think it's been observed to provide an organism with a wholly new beneficial trait which is probably why Evolution is still a theory. Theories are never complete until they become laws and will never become laws until their inherent problems are resolved.
Even if Evolution holds true the Bible is silent on the issue of what processes created the stars or life itself, so Evolution in itself does not falsify or verify the Bible. It does seem, though, that the Bible upholds Paleontology's chronology as well as the Big Bang. If you want to tackle more falsifiable issues to strengthen your faith then we can study contradictions in the Bible as well as fulfilled prophecy.
As a side note I don't buy into the belief that scientists are without preconceptions or prejudices. All humans have influences that shape their world-view and how they interpret data, especially someone who doesn't want to die or - on the opposite side of the fence - someone who lacks funding for research or who doesn't want to be held eternally accountable to a higher power they disagree with.
