On the question of the Biblical flood, here are a few comments I posted on another thread some time ago.
1. The Biblical flood would only have wiped out land animals- all fish, etc. would presumably have been fine. So there appears to be some ambiquity in the Genesis account since it states that the flood wiped out
all living things, but doesn't explain whether fish and other sea creatures died. It also doesn't explain why the presumably thousands of fishermen and others that would have been out in the ocean with their boats died, or where the second dove that Noah sent out got the olive branch that it returned with.
2. While I am not aware of any scientific evidence for a world-wide flood, there is very convincing evidence of a massive regional flood in the Mediterranean Basin. Since this area was heavily populated at the time, and likely the cradle of civilization, this event would have killed large numbers of people and land-dwelling animals. This event is described in more detail in a number of scientific publications, and also at this Christian web site:

In a nutshell, northward movement and collision of the African Plate with the European plate at one point in the distant past closed off the Strait of Gibraltar, which then allowed the Mediterranean Ocean to basically dry up (more water evaporates from its surface than flows into it from rivers). Presumably, many people living along the shore of the Mediterranean would have followed the receding waters downhill, setting themselves up for what was to come next......
As plate movement continued, and downwarping of land at the present-day location of the Straits of Gibraltar occurred, Atlantic Ocean water started to flow back into the Mediterranean Basin. The initial flow would have quickly increased as rapid downcutting occurred, thus creating a massive flood that would have rapidly engulfed the entire Mediterranean Basin, and overwhelmed all living things there.
3. There would have been a time in the Earth's distant past, before plate tectonic activity pushed up crustal material to form mountains, when the Earth would have been much flatter, and floods would therefore have been able to inundate much more land (assuming, of course that ocean water was already present in sufficient quantities to cause flooding). Heck, since about three quarters of the Earth's surface is water, maybe there was a time before mountain building occurred when only a very small portion of the Earth was above sea level, and it would have been much easier to overwhelm the air breathing creatures, including man, that were crowded onto the limited land available.
I have no doubt about the authenticity of the Bible, and therefore no doubt that God created some sort of massive catastrophic flooding event that wiped out a good part, or maybe even all, of mankind, and a bunch of other air breathing creatures. It is intriguing that the story of a world-wide flood is mentioned in other religions and in the legends of some First Nations people.
However, beyond these two truths, I don't pretend to understand the literal story of the Genesis flood, and have to assume that we are not yet to the point where we can correctly interpret what it says in the Bible about this event.
As little as about 100 years ago, the concept of a massive Mediterranean flood, and the mechanism of plate tectonics that created it, would have been considered preposterous. Now, though, our past assumptions have been shattered by newly-discovered knowledge, and what was once considered a myth is accepted to be reality. Science has had a habit of doing that (see geocentrism) to us numerous times in the past- forcing us to re-examine our interpretations, but, when a better explanation is established, still keeping the basic tenements of our Faith intact, or even strengthening them. I think we need to learn something from that.
So I view the story of the Biblical flood with interest, but have no doubt that our present interpretation of that event is not likely correct.
On the question of the age of the earth, I believe there is overwhelming evidence from many independent sources (radiometric dating, speed of light and size of Universe, ice core studies, stratigraphic studies, etc. etc.) that the earth is very old; certainly much, much older than the 10,000 year age that creationists seem to believe in. At the same time, I believe the Bible does not provide a clear-cut statement about how much time was actually involved in the 6 days of creation, and therefore to rigidly hold to a literal interpretation of the Genesis account is just that- an interpretation.
On the question of evolution, I believe there is overwhelming evidence that evolution occurs- but how far back it actually goes is unclear, and how that first living cell was "accidently" (in the words of an atheist) created from inorganic material AND, at exactly the same instant of time, was given the ability to reproduce itself without the intervention of a Creator, is also not something that science can explain.
I also think God makes it very clear in the Bible that the matter of time is really pretty unimportant in the overall scheme of things (see Acts 1:7) and that with this issue, and many similar ones, we need to be careful to discuss them with a proper persepective. Much more important is to focus on issues that directly affect your, and others, salvation.
