Even Big Bang Theory suggests holes in the light distance thing listed above.
Nobody knows what happened scientifically in the creation 6,200 years ago or so.
If you see a wall of solid concrete, but never saw a cement truck, or saw one dump concrete, you might have all kinds of suggestions and theories about how that wall got there.
First of all, I'm no expert in physics, is there a source on the first point? Just that the idea the first person suggested sounds fairly reasonable, I'm wondering what the evidence is against it?
Big Bang suggests that in an instant, stars, planets, all kinds of materials and energy were spewed from a single point into a gigantic size, and continued to expand at both, increasing velocities in some places, and decreasing velocities in others. The speed of light could absolutely not have been uniform back then.
If you search for it, you can find scientific data that shows that the speed of light isn't an uniform thing right now, long after things have stabilized. Google and Youtube search on "Sheldrake, speed of light."
Secondly, we have a pretty good idea of what happened 6,200 years ago. In geological time 6,200 years is a blink of an eye. In fact, humans had been around for a while 6,200 years ago, and had already developed agriculture and basic civilizations. The lineages that would develop into modern day humans first diverged from chimpanzees(our closest relative in evolutionary terms) 6,000,000 years ago, and anatomically, behaviourally modern humans had developed by 50,000 years ago.
This is the exact thing that we are talking about. Why do we and scientists think like this?
Pottery dating based on civilization backwards-in-time extrapolation can only go back more-or-less accurately, about 4,500 years, if that.
Genetic and mitochondrial dating suggest a divergence from the original woman to be not that far back in history.
When you look at the basic scientific papers by those scientists who have done dating studies, all of the papers use limiting words like "if" and "maybe" and "we think" and "possibly," and even direct statements that tell us that they are only speculating regarding the time of things.
Evolution is mathematically impossible -
https://bitcointalksearch.org/topic/the-mathematical-impossibility-of-evolution-1454732. Google it and you will find that even the debunkers of the impossibility math show by their language that they are not sure even when they say that they are sure.
I don't really see the idea of the last point - we have a lot of experience with molecular and geological dating methods as well as study of the fossil records that gives strong evidence for a lot of the information we have now about the history of nature, the Earth, and our own species and its evolution.
If there wasn't any C-14 in the atmosphere beyond 5,000 years ago, carbon dating suggestions would only be off by billions of years. Nobody knows for a fact that there was C-14 in the atmosphere back then. The closest we have is the Bible record that suggests that there was a high-water-content upper atmosphere which would block the cosmic rays necessary for converting nitrogen into C-14. The Great Flood of Noah's day - which is referenced in writings and cave drawings are and traditions of many peoples around the world - could easily have destroyed the upper atmosphere water curtain, so that C-14 in the atmosphere is only a recent thing. The point is, nobody ever went back there to analyze what it was like back then. And none of those people left us a clear enough scientific record so that we know. We only guess. Carbon dating is all a guess.
How long does it take to fossilize something? Google it. The standard suggested scientific minimum is 10,000 years. There is present day evidence that it can take as short as a few months. But here is the big question. How long does it take for something to rot? Yet in some of the so-called ancient fossils we see delicate tissues being preserved. Delicate tissues don't last for even 3 months in the presence of the putrification process. The point is, fossilization is a very inaccurate science. It is another science that suggests something that we only guess at.
The point is, somehow the sciences that we use to determine the age of the earth, have been treated as fact when there is little if any fact in the results. We could talk all day on this. But you can easily search the Internet for debunking and attempted debunking, this way and that, to see for yourself that we really don't know.
