How does this question make logical sense? How is the fact that Earth could be destroyed by the Sun in 5 billion years a relevant factor in the disproval of evolution and step by step natural selection?
One of the problems with the current version of evolution, is it cannot predict the future. The current model is more based on 20/20 hindsight approach; empirical model. The model does not help us see the future, but rather can only compare the past to the present, to see that evolution happened. This is not exactly the most advanced type of science. This is expected since it uses the same math used by factories, gambling casinos, pollsters and politicians; fortune telling approach for the future.
Fossil evidence gives us old bones so we can compare these with modern bones. Based on these comparisons we can see a change we call evolution. The DNA evidence works the same way. But what will be the future of modern life is not possible using that empirical strategy. This is because the theory, as is, is not fully rational. A patron to the casino has more hope than logic but can tell you every lottery winner over the past year.
We can send a rocket to the moon, anytime in the future, since the math of projectile motion, allows us to draw the curve from the past to the present and into the future. Only a rational model can do this. A semi-rational model breaks down when the direct data is lacking. This is typically the future. The biology is weak when it comes to a rational explanation of the future of evolution. It is more like wait and see, since the future is beyond the capacity of the theory. It assumes the future is like playing the lottery. We can wish and pretend to spend the money, but it may not pan out that way. This is not bad for 19th century science, but it needs an update to be called 21st century science. The tools are there, but the theory is not quite there.
As an applied scientist, that uses pure science as a foundation for developing new ideas, the current approach to evolution is not a useful foundation to build upon. An applied scientists needs to make things that can function in the future and not just the past or present. People do not want another Model T. I can use projectile motion equations, since these are more advanced; rational. Pure scientists may not see this, but an applied scientists knows that you should not to build on a swamp that ebbs and flows, unless you can figure out how to set the footings much deeper than the bottom of that swamp. We need to hit ledge which is beyond current theory. I did find what I needed, which is life and water.
In the 1950's, science was interested in how life formed on earth and other planets. All types of research appeared to that end. One area research tested cells, with the variety of solvents, that had been postulated to be able to support life on other planets; the solvent lottery. What they found was only water allowed life to appear from these cells. All the other solvents were disruptive, that nothing worked in any cell; DNA to enzymes, and no life was evident. This data showed life was not a lottery, but rather there was a cause and affect between water and life on earth. Unfortunately, common sense reason was ignored for casino math. Here we are 60 years later and still playing dice and cards.
The data from those experiments showed that since life on earth had evolved in water, all the organic components in the cells, were tuned to water. None of the cells or their internal components worked in other solvents, because they had all evolved in water. Water set the chemical stage, from day one, so everything will forever remain specific to water. Like in evolution, the desert or the polar tundra will determine how life needs to change to be optimized in that setting. There is a cause and affect. Water did and does the same thing at the nanoscale.
Biology is very organic-centric, but the data showed that water was leading the organics from day one; natural selection in water, so everything could and world forever be tuned to water. I expect this to hold true today and the future. This is the deeper footing below the swamp, on which to build. Water does not move in the ebb and flow of the organic cards. Water is persistent and does not change like the organics. Dinosaurs drank the same water as us and the future of life will use the same water on earth to make their cells work properly. And water will continue to be the selective referee for all evolutionary change. If we ran the 1950's experiments today or tomorrow it will end the same way in spite of any organic evolution. Water marks the cards and loads the dice.
