None of those are theories. They are presently observable fact in the here and now. Intra-species evolution isn't. The other realms may actually exist, but they are not provable with existing instrumentation. They are in the same category of notion as evolution.
You're telling me that you can see germs and atoms?
(No, deducing them from what you see in an instrument doesn't count, unless you accept that equivalent deductions from measuring the age of fossils also counts.)
