What is the definition of “evolution” you’re railing against as unscientific? Maybe a better question is what do you think evolutionary biologists spend all day doing? Patting eachother on the back for figuring out the bug story? No, they study and test lowercase “e” evolution, which is the truly scientific evolution, and is based specifically on the mechanism of passing or not passing variable traits from generation to generation.
Thanks for asking - it's a good question since I was vague on the broad topic of "evolution".
I classify the big picture evolution as "just a theory" because the rigor of the scientific method has not been employed - where organic elements became living creatures through random events, then it propagates, and where one living species became another (a fish becomes a frog and a rat becomes a bat).
In the study of genetics, where adaptation can be observed, I readily acknowledge that the scientific method is employed. That's one of the amazing things about life on our planet - it has built-in flexibility to survive and thrive. As humans, I believe we are all descended from Noah's family. As we fanned out across the globe, different adaptations created different races from the same human stock.
