Engineers use physics every day. Biologists never use the mythologies of evolutionism.
You've been misinformed about engineers and biologists. Most of the time, they look it up in tables, but even aside from that, you're wrong. Evolutionary theory is used regularly by agronomists,(predicting the fitness of new varieties) drug and pesticide companies,{overcoming the evolution of chemical resistance) and doctors (designing protocols for minimizing the evolution of antibiotic resistance).
Among other things.
And that is why we find so many Creationist biologists practicing in the field today without the least "problem".
They are exceedingly scarce. The last world-class creationist died about 1900. There hasn't been another one. I knew one when I was an undergraduate. But only one.
Evolutionism failed to find any support in hard science of any kind
Odd. Stephen Hawkings thinks otherwise. Do you suppose he's a better authority on "hard science" than you? BTW, the Nobel laureate physicst Irwin Shreodinger in "What is Life", admitted that biology was a harder science than physics. You've been misinformed on that, too.
much less the natural sciences and so the members of that belief system have tried to co-opt basic principles of biology having nothing to do with the salient "distinctives" that are required for evolutionary biology to ever be proven "true".
Of course "proof" is never part of science, which is primarily inductive, and depends on evidence. However, there is a great mass of evidence from a large number of sciences, which is why scientists of all disciplines overwhelminingly accept evolutionary theory.
As we have already noted - the classification of the varios species "did not wait for an evolutionist to posit reptiles turning into birds before it could segment the existing observable life forms". The same is true of the function of biological "systems" - they are "Freely observable" without having to speculate that a hominid turned into a human one day.
Humans are hominids. Formerly, non-human ancestors were known as hominoids, but all are now under the classification "hominines".
As it turns out - there is not one single "tenant" of evolutionism "that is required" to make any observation or testable prediction in biology today.
No, that's wrong, too. For example, it was predicted, on evolutionary theory, that bacteria would rapidly become resistant to penicillin. They did. Evolutionary theory predicted dinosaurs with feathers, whales with legs, and reptiles with mammal characteristics, all of which were found after the prediction. You've been misled again.
And so - creationists that accept that after 5 "Evenings and Mornings" God then created mankind - Male and Female by forming them of the dust of the ground - have no need to "appeal to evolutionism" to see and observe biological sciences today.
Religion, depending on faith, has no need of science.
