WELL...PROVEN "SCIENTIFIC FACTS" DO EXIST
There is nothing 'scientific' about any fact. Science is a set of falsifiable theories. A fact is either just a fact, or it is not.
(EG.: WATER, IN ITS PURE FORM, IS ALWAYS H2O).
Not a proof. Not a 'scientific' fact. Simply a definition.
MACRO EVOLUTION IS NOT ONE OF THEM.
The Theory of Evolution is not a theory of science. It is not falsifiable. One cannot go back in time to see what actually happened. There is no theory of science about what you call 'macro evolution', since no new species has come about as a result of natural evolution, that has been observed as of yet. Man has created new species, but none have appeared naturally, as far as has been observed and published.
JUST BECAUSE SCIENCE CAN'T PROVE EVERYTHING, DOESN'T MEAN IT CAN'T PROVE ANYTHING.
Yes it does. Science is an open functional system. A proof is not possible in an open functional system. Proofs are only possible in closed functional systems like mathematics or logic. It is not possible to prove any theory (scientific or otherwise) as True.
MACRO EVOLUTION BECOMES LESS and LESS LIKELY AS WE LEARN MORE ABOUT GENETICS.
Here I agree. Once unnatural selection forces are removed, the base critter evolves again over time.
Fruit flies in all the variations that survived in the lab environment return to your basic fruit fly.
Dogs with all the species that we have created return to the wolf, given unplanned dog sex over time.
Cats with all the species that we have created return to your basic cat, similar to something like a cougar, given unplanned cat sex over time, or the smaller South American cat (also found in Africa), that all house cats stem from.
This has been observed time and time again, this direction of evolution.
Apparently, evolution tends to favor returning to the naturally occurring form, rather than continuing a deviation.
So the Theory of Evolution, which states that present day life evolved from more primitive life forms, seems to have problems. Of course, it's still not possible to prove it False. It is and remains a circular argument...and a religion.
