Theories are tools used to explore and explain the natural world. As any tool from hammers to fire to nuclear fission, they can be used for both good or evil. That people attempt to use the theory of evolution to justify, say eugenics (a common anti-evo cannard), does not invalidate the mechanisms of variation and selection.
I also think there's more gone on--on this globe--in eons past that are not even hinted at in the fossile or any other record we have detected.
I don't mean to insult your intelligence, but you are aware that this can only be a matter of personal belief? And that because we have not detected these events, even indirectly, the realm of science must necessarily remain silent on the matter until evidence of such is brought to light?
