They probably grew hostile because the answers are in the books if you read them and are online.
I would take my kids out of any school that taught creationism as a scientific option because I do have a background in science.
You should do the reading and then you'll know why. The answers aren't that difficult to understand.
I suspect that their hostility came from something else. Perhaps from their discomfort over Flagg's asking the questions for which they had no answers. Questions that their own minds might never have even pondered.
Science isn't just about looking things up in books or online. It seems Flagg had already done that.
Science is
supposed to be about asking questions. Somewhere along the line, science devolved into more of a petty turf war. Questions which might actually challenge dearly held notions are met with hostility.
Much like the Global Warming fiasco, "scientists" will exert all possible pressure to stifle questions that would expose the significant gaps in their reasoning. On the other hand, real
Scientists will continue to raise the questions.
Do you think Darwin got his ideas from text books (or online)? Or did his observations about the world inspire him to ask brilliant questions?
With your background in science, why don't you explain how a bird wing would evolve by way of
random recombinations of DNA sequences.
Consider the thousands of sequential mutations that would need to occur in order to arrive at the finished product. Hollow bones, for example.
You may want to consult with an aeronautical engineer to get idea of how many small tasks are involved in the process of designing and building a functional aircraft wing. Get any one of them wrong, and the plane ain't gonna fly.
And how would each of these incremental mutations given the creature a competitive advantage. Hollow bones, for example. Necessary for a bird to fly. But in the millions of years between the mutation that resulted in hollow bones, and the first pair of functioning wings, wouldn't it be a disadvantage to be breaking your fragile bones every time you tripped over a rock?
Not to mention dragging around those pre-wing appendages for thousands of generations. How would those not-quite-arm-not-quite-leg-not-quite-wing things help those creatures avoid or fight off predators more effectively?
I'd appreciate the link to the website that explains that for me.
