Would you prefer that I simply pick one of his errors and address that?
Or how about I take a look at one of your claims:
"Given that there is no evidence that atomic decay has been anymore constant than the speed of light or 14C accumulation, I've no problem with that time frame. Science provides no reason to question my belief." (From the previous post)
The earth currently gets much of its energy, in the form of heat, from the sun. The rest of the heat energy comes from the decay of materials on and in the earth. If the speed of light was initially 'faster' than it is now, energy from both the sun and radioactive materials would have been higher as well. If you calculate the speed that light would have to have reached to result in light from the edges of the universe reaching us in 5000 years (I'm assuming that the light had to reach here before star positions were documented) energy levels from the sun and from underground decay would have been too high to allow life to exist for hundreds of thousands of years.
I invite you to do the calculations yourself.
Here are a few things you'll need to make that calculation:
1. E = MC2 (Of course)
2. The distance to the farthest away light source. This will be at least 50,000 light years away since we can now directly measure that distance with the use of geometry (parallax) and highly precise measuring equipment. We can use parallax measured distance to calibrate other measuring distances. Distances out to 170,000 light years away (SN1987A) have been measured indirectly and can also be used to calibrate other measuring methods. Using these calibrations calculated distances much farther out can be considered highly accurate.
3. The creationist age of the Earth. Somewhere between 6000 and 10,000 years I believe.
4. The calculated curve of light speed determined from the initial creation time and distance to farthest light source to the current light speed in light of the rate of decrease creation scientists believe they have observed within the last 100 years.
5. The mass of the Earth (To determine the cooling rate)
6. The amount of energy the Earth currently receives from the sun.
7. The amount of energy the Earth currently generates in its core.
8. The calculation of the initial energy from the core based on the current temperature of the core, the cooling rate of an Earth sized mass given the energy dissipation rates based on the previous light speed curve.
9. The calculation of the initial energy from the sun, based on the light speed curve.
10. From there you can determine the initial temperature of the surface of the earth 6000 years ago and the length of time it would take to cool down enough to support life.
I have probably missed quite a number of conditions and calculations necessary but I'm sure others will supply those. This should give you a start in any case.
Don't forget to show your work when you present your results here.
If the earth had a canopy at the time which filtered a lot of the higher spectrum, I don't think you can sustain that argument. Further, you'd have do know the output of the sun at that time. In short, you're assuming a lot of things, again, that you can't sustain. That's the problem with assumption. Once you start, that's about all you get done.. assumption.
