A scientific theory is not the same as verifiable observation. You keep bouncing back and forth between this confusion. We have a lot of observation, and that observation adds up to a theory (evolution, plate tectonics, gravity, etc). These terms give context to the observable data. You can't observe evolution happening because it takes tens of thousands of generations for one species to turn into another.

Look at dogs. A pug is a descendant of a wolf. What if pugs continued to breed for 1 million years? Would we still call them wolves, or even dogs? Evolution is the best theory for why a wolf can become a pug. The bible can't explain that, or make predictions about the fossil record. Genetics is part of evolution.

There is no more evidence for The Bible than any other religion - if you want to start that slippery slope. Even if The Bible was a literal eye-witness account you still wouldn't be able to rule out aliens doing it all (or errors). It's not a logically sound explanation.
