So how and why did the "past state transformation" occur? Answer in as much explanatory detail as endogenization provides, or concede that your idea is nuts.
Proabably a little over a century after the flood of Noah, in the days of Peleg. (when the earth was split)
Why? Well I am sure God has His reasons. I can notice that wicked man doesn't live as long. That is one result. I notice that no spirits marry women any more and live here on earth.
If you thought there was some fluke reason like some 'natural' degradation of our present state or something...forget about it!
The future is the key to the past. (not the present). So, we can ask why the state will change again in the latter part of the Tribulation or start of the millennium? The answer is that God is in control.
Science is so woefully ignorant that it is not even cognizant aoout anything other than a blind belief that this temporal state must be all one looks at, models on, or allows.
