Well I'll be delighted to dad. Below I will describe through three independent methods how we know the past has been he same.
What I provide is physical evidence based on the laws of nature. What you have suggested is a made up fantasy world. You are the only one doing coloring and tainting.
1. Decay rates:
a. When a radionuclided decays it emits energy, therefore heat. For decay rates to have been higher in the past to yield the ages we get with rocks millions or billions of years of age in only 4,300 years (since the flood), the earth would have become completely molten. Thus absolutely no life could have existed before the flood.
b. In chain decays, for example the uranium series, goes through 18 separate decays before becoming stable as lead. Each of these separate decays forms a different isotope with a completely different decay rate. Thus, any rocks formed before said flood with said accelerated decay rate would show different ratios between each of those 18 isotopes than those formed after said flood. All rocks formed before and after said flood (said change of physics) would show different ratios in the decay chains. And uranium is not the only decay chain, there are others and there are no decay ratio changes.
