Sorry, but the Bible consistently describes the sky as a vaulted ceiling that holds the waters back: http://contradictionsinthebible.com/genesis-1-waters-above-firmament/. This was exactly the kind of conclusion that we would expect an ancient thinker to arrive at.
The ancient failure to realize that light came from the Sun also makes sense, since they did not understand how light rays disperse in atmosphere. Since they observed that daylight could be present without a direct line of sight to the sun (before dawn, or on a cloudy day), they thought day and night could exist without the sun and moon. Thus Genesis tells us that the two "luminaries" were simply for "shining" like torches, and for marking the change from light to darkness, but not that the sun was the cause of daylight (they also thought the moon emitted light, instead of reflecting the sun's light).
The serpent was indeed later identified as Satan, but only by Christians, not Jews. Religions are entities which evolve over time. Just as Christianity was initially a form of Judaism before it deviated under Paul's teachings, so Christianity has continued to evolve. For instance the New Testament has little to no inkling of several later Christian doctrines like the Trinity and the Immaculate Conception. We can even see the story of the life of Jesus evolving when we read the Gospels from oldest to newest.
Widespread stories like that of the Flood are just as easily explained as "people everywhere have experienced floods". There is simply no special knowledge to be inherited from our ancestors. All the records we have of their beliefs are scientifically and morally primitive, and that includes the Bible. We can see a steady increase in knowledge as we look at each successive civilization throughout history. Jews did not have any special knowledge, for instance, that the earth was round despite claims that their scriptures say such a thing, nor did they grasp the true nature of the sun and moon.
Everything that we reliably know and upon which we have based our civilization was learned by observation and experimentation -- science -- not received through divine revelation. God apparently did not see fit to leave even one useful piece of scientific information in his book, such as how to cure diseases, leaving people to suffer from polio, for instance, until the 20th century when the vaccine was invented.
It will always be possible to represent Bible verses as being scientifically sound if one is willing to layer enough additional explanations on top of the actual texts. It all hinges on how hard one is trying to believe that ancient sheepherders actually knew more about our world than we do today, as scientists do things like study the cosmic microwave background for evidence of multiple universes.
Do yourself a favor and read what scholars have written about the Bible -- not these unqualified apologists' web sites. Like science, Bible scholarship has advanced a lot since the 1800s, though fundamentalists don't know that.
