Do you have any information on how the Earth could be six thousand years old?
Well, I can't have something that doesn't exist, so no
In the first seven days God created everything (which, obviously, includes man). Start tracking the dates of human history, and you have 6000 years. Thus, the Earth is 6000 years old. Humans have been around since the beginning of time. Along with the dinosaurs and other animals.
For one, human history extends back further than 6000 years. Most of it wouldn't be "history" in the sense you're thinking, which I'm guessing is written records. However, we have knowledge that Sumerian civilization existed around 7,000 years ago. And we have also found artifacts (and skeletons) of modern humans (homo sapiens) that date back far longer than 6,000 years ago (think tens of thousands of years). So no, the study of history, if you mean history by people other than Young-Earth Christians, does not support the idea that human history, or even human civilization, is only 6,000 years old.
Evolution states that the transformation from a red giant to a white dwarf star takes billions of years. Here are some records of the white dwarf Sirius:
Egyptian hieroglyphs from 2000 B.C. described Sirius as a red star.
I forgot to mention this earlier.
Apparently you accept that 4,000 years ago, Egyptians had a sophisticated civilization with pyramids and all the like. Even though this civilization would have been completely destroyed by the flood you say happened around 4,000 years ago. I realize you said that the flood was 4,400 years ago (apparently 400 years is long enough to completely rebuild civilization). But notice also that the Great Pyramid is also about 4,500 years old. I guess that's not inconsistent, altho it's a bit strange that it's so intact despite the flood. Anyway, the Great Pyramid was built for Khufu, and we also know about the rest of 4th dynasty that followed after him. Right through the time the flood happened.. So... either you accept the dates that show that Egyptian civilization continued uninterrupted through this supposed flood, or you must not consider any dates regarding Egyptian civilization accurate, because they use the same methods to date all those things as well.
Moving on from egruntz...
I'm not denying the fact that there are still hunting and gathering societies up until this day.
My point was that "progress" is not an inevitability, so your suggestion that human kind would have definitely progressed more than it has if we had been around longer is unjustified.
And I notice you did not respond to the part where I pointed out that human progress has been accelerating. If I applied your reasoning to some other idea (let's say, that the Earth is 700 years old), then we would get this:
If we look at the difference between "1600 CE" and "2000 CE", the difference in technology is huge! There's no way humanity is 6,000 years old, because we would have progressed far more than we have now!
The rate of progress in the past couple hundred years has been possible because of the large human population (more people to come up with ideas), less disease and malnutrition and so forth (which reduces the health and intelligence of the people, not to mention taking lives), our agricultural society (which produces a food surplus, which allows some people to work as, say, engineers and scientists) and our prior knowledge. 2,000 years ago, progress was much slower because we had a smaller population, with a smaller proportion of that population involved in agricultural societies, with less knowledge and less knowledge of methods of increasing knowledge (scientific method, for example), and thus were weren't the factors that contributed to the rapid progress of the past couple centuries. And before then, before we even had populations in the millions, before there were agricultural societies, before we had knowledge about much of anything, progress was essentially nil because you had not that many people to innovate, people had to concentrate on getting food, not coming up with new tools or what have you, and died of disease and so forth. Which is why it took hundreds of thousands of years after humanity evolved to about our current level of intelligence for human civilization to progress to the point it has.
Progress enables more progress, so it is not linear, but geometric (exponential). Thus your assumption that the rate of progress over the past 6,000 years is in any way reflective of what we would have expected in the time period before that is flawed.
At any rate, do you have anything to say about the various methods of radiometric dating?
