Evolution is absolutely a religious belief. You can’t prove it, can’t observe one species become another species, can’t repeat it or set up testable events. It is simply an act of faith that Evolution is “real”.
If I plate a bacteria out, blot it on ten different plates - then subject it to ten different stresses - I will get a heat resistant strain through evolution, a cold resistant strain through evolution, an antibiotic resistant strain, etc, etc.
No scientific theory can be proven. One cannot observe the Bohr model of the atom, but the Bohr model of the atom is of use. If someday it is replaced with a mores useful model - horay! Until then it is the only scientific model currently in use.
"There is no god but the failed theology student Charles Darwin and Stephen Hawking is his prophet (or profit) or whatever." Many of them also believe in "global warming" or "global climate change" or whatever this week's pc term for climate bullshit may be.
