If so, then there should be some sort of scientific evidence for such a change...
If we look at the future, when the new heavens come, what evidence of change will there be? Things will last forever, no longer be in decay, the spirittual and physical will be together. God, a spirit, for example living right there with us. Our bodies, like that of Jesus both spiritual and physical then. If we remember, He could be touched if He wanted to, He ate, and was physical. He still has the wounds for example. Yet, He passed through wallls, appeared and disappeared out of sight, rose up to the sky, etc., and was now immortal. He was also spiritual.
If we imagine a whole world, or universe the same, merged matter, we can see it is simply totally different in a lot of ways, yet the same in many ways.
If such a world also existed in the far past, and the spiritual part was seperated temporarily, leaving us in a physical only state, what evidence of the change should we see?
I suggest that light would be different, also, therefore also plant growth rates. Also, matter would now be in a state of decay. These things we see!! Then we see other changes in matter, like how physical only matter takes a long time to cool. But in creation week, for example, there was a massive planetary movement, where the dry land got seperated from the waters. This means heat. Yet the same day plants were created! It cooled fast then. If the continents moved apart in the days of Peleg, as some Christians theorize, that too would have produced tremendous heat. If the flood waters came up from the subteranean, and down from the heavens, that too, would have produced a lot of heat, if all we were dealing with was physics. If it did come down, that is evidence of a change, as it could not happen in the present. We could go on, but that is the idea.
The change was not a physical universe, we are the change, in this temporary, one day to pass away, physical only universe. The evidence we need is not available from physical science, because they assume it was always the same, though can not prove it, of course, cause it was not the same.
My best opinion on the date from what I read in the bible, was about 4400 years ago. Or about a century after the flood.
But where did this "different nature" come from? And how is it, in a practical sense, any different than claiming a hatful of megamiracleas?
The different nature was the CREATED STATE of the universe. The normal, eternal state will be here again, when the new heavens the bible speaks of appear, and these old heavens (physical only) pass away. We will, again, have no decay. We will, again, have another kind of light. The bible examples this in the New Jerusalem, which is lit with light from God. Spiritual light.
