Haha at the long day and night thing. It's the greenhouse effect that keeps the temperature at an relative temperature throughout our 24 hour day. Not whether or not the sun is blaring down on us. Yes, that affects the temperature, but it wouldn't "cook" us and it's not going to get 240 degrees below freezing. Look wAY up north, those guys go a month without sunlight and the temperature doesn't get that cold and they want to say it's going to happen everywhere else?
I'll admit that's all I read but that seemed to be enough.
EDIT: Well, I read the part about the earth's tilt. It's space, and you're talking about two spheres with the sun and the earth. Grab two balls, and start rotating one up and down. The sun doesn't just shoot rays directly at earth, it emits them everywhere. Yes, the tilt affects seasons, but so does the elongated revolution around the sun. Ideally, there'd be a perfect circle traveled around the sun at the distance we are in spring. That would kick ass.
Before the effects of the flood on the earth's axis, due to the atmospheric conditions scientists pull out of air bubbles found in "pre"-historic amber and according to what dinosaurs would need to survive, we know the earth's atmosphere had something on top of it pushing down on the atmosphere which created about twice as much air pressure and we had a bit more oxygen and a few little differences in the mixture of particles. This allowed dinosaurs to grow to the insane sizes we find them in the fossil record, not to mention how everything in the fossil record is much larger (such as crocodiles and sharks, etc). This proves the greater air pressure of the pre-flood world, or "pre"-historic, as some think of it.
Whatever was pressing down on the atmosphere, in theory, also blocked the sun's shortwave radiation, which is what causes things to heat up around here. The cracks in the oceans are where the flood waters came from, underneath the crust, according to the Bible, where most of the water was located back in that time (so we had maybe a small ocean toward the south of the globe, and mostly land with rivers back then, it would seem, theoretically).
If that were the case, then the earth was built like a perfect nuclear reactor, providing its own internal heating and watering system (since there wasn't any rain yet, which makes perfect sense, because the sunlight heating the atmosphere is what causes evaporation and clouds, etc.). Therefore, the globe would be equally heated all over, the canopy over the atmosphere would block the sun's heat, but let in the light (scientists have figured out how to replicate the canopy to cause this effect), and we'd have warm climates all around the globe. Also, we can track exactly when the wobble of the earth began, which means it is likely that the earth was straight up and down, and then the water's burst forth causing an off-balance to the spin, which caused the axis shift. It just so happens that when we use the mathematical equation to track the wobble of the earth backwards, we see that it began 4400 years ago, which is exactly when the Bible places the flood's occurance, as do many worldwide cultures (and we see 217 different cultures with very similar worldwide flood stories). We can also track the growing of the Sahara desert, because it grows a few feet each year on every side (meaning plant life on its edges dies out and turns to desert), and it tracks back to its beginning being about 4400 years. There are other markers around the world that indicate a worldwide flood about this time, as well. The odds of this being coincidence are astronomical.
And finally, we know the earth's temperatures were about the same all around the globe right before this global flood, because we find wooly mammoths near the North Pole, frozen, standing up, with green vegitation in their mouth being chewed and in their stomachs. We also have found a man in only a loin-cloth near the South Pole in Antarctica, standing up (that's hardly winter-wear). So the clothing of the man proves warm climate (of which our wobble never could've supported for that region of the planet), and the mammoth's green vegitation proves a warm climate there, as well. The fact that both man and mammoth were frozen standing up means that whatever happened to them happened in literally seconds, freezing them solid before they even realized what happened.
The theory is that this canopy around the atmosphere collapsed during the flood either due to the extreme weight of the crust pressind down on the water causing it to shoot up and break the canopy, or, a meteor shattered it, causing the Gulf of Mexaco (which is firmly believed to be a meteorite crater). I opt for a combination of both, with the meteorite triggering the crust break, causing the flood, which further hindered the canopy. Also, the colder ice is, the more magnetic it becomes, and the earth's magnetic energy (the poles) was approximately 2.75 times stronger 4400 years ago (because every 1600 years, the magnetic force loses about half its energy). The magnetic force likely pulled the ice moreso toward the poles, and this is why we find only the center of the globe having little ice while the top and bottom of the globe had tons of ice, according to evidence of glaciers pulling north as they melted. It would seem that glaciers came down as far south as the mid-US, if I'm not mistaken. Man could've easily survived in the middle of the globe, as could animals and sea-life. As the ice melted, the water drained from the land and went to the recesses near the cracks (i.e. - where we now have oceans, obviously). You'll notice that the trenches in the ocean floors are all connected to a central burst point.
The evidence of a worldwide flood would be millions of dead things, buried in layers of sediments, all over the earth, just like we find layers and dead things in those layers at the bottom of standing bodies of waters such as lakes. Mt. Saint Helens laid down what appeared to be 360,000 years worth of layers in a matter of 2 weeks after the explosion. And when we look at the actual layers in the earth, we see bones settled through multiple layers, not just in one single layer, which would mean that those bones lasted through millions of years till they were fully barried and fossilized, which makes no sense. Normally, if there were no flood, the carcuses would lie on the ground and break down and turn to dust eventually, due to atomspheric exposure. That's not what we see in the evidence.
What we do see are fault lines with tons of bones around them, as if water were draining back into the earth through the fault line, pulling the bones with it as it went, but the bones were buried just below the surface on their way to the fault line in the drainage. That's why fault lines (sink holes) are the best place to find "dinosaur graveyards" where people barely have to dig below the surface to find the bones. However, the torrential waters broke apart the carcuses so badly that it is incredibly rare to find a full skeleton.
The theory makes much more sense with the proof. People just aren't very good at laying out all of the parts of the theory quickly in a nice neat package that explains it and the proofs well.
