But the truth of this matter is that science does verify, more and more each day.
Indeed, all the basics of evolution theory are confirmed daily by scientists working in related fields, including innumerable predictions, such as these.
Astronomical and geological observations confirm the Deep-time scales required for evolution.
Physics and chemistry confirm natural "complexification" of organic molecules.
Biology confirms both the processes (DNA modifications & selection) and results (speciation) of evolution.
All that together makes evolution increasingly observed fact, explained by innumerable-times confirmed theory.
As for your straw-man argument that "no bacteria evolved into a whale", of course not.
But bacteria apparently did evolve into Eukaryotes, about two billion years ago, which became multi-celled animals around 800 million years ago, arising into mammals circa 225 million years ago which branched out into today's 5,500 living species, including whales.
That's the theory: innumerable small changes accumulating and selected over eons of time too large to even imagine.
What's ridiculous is any suggestion that all this happened strictly by random chance, with no Divine plan or interventions.
Nature is, after all, God's creation.
my argument is not a strawman. to call it such is to cheapen reasonable discussion. i chose an example to illustrate the inherent problem with applying the scientific method to macro-evolution.
if you prefer a narrower focus, then please devise an experiment where we can see one species evolve into another species. i’ll define species as organisms sufficiently changed as to no longer be able to interbreed successfully.
