Darwin’s theory was built upon the idea, now proven false, that cellular life was simple. The discovery that even the cell is irreducibly complex put paid to that theory. The discovery of DNA worsened things because mathematics entered the scene and calculated the odds of accidental life.
So there appears to be some sort of evolution going on since life forms change. On the other hand admitting that it appears that there is intelligent design doesn’t prove that the Bible is right either. That would be another leap in logic not supported by facts in evidence.
I believe that's called Faith.
But Darwin's theory of speciation through evolution is based on no such thing.
In fact Darwin knew nothing about inherited traits, much less DNA.
He merely proposed that speciation occurs over long periods of 1) descent with modifications and 2) natural selection.
Nothing discovered since Darwin's time falsifies his basic theory.
As for intelligent design, that is a given for believers.
Only the "how" of it is a matter of discussion & disagreement.
