Arent Natural selection and genetics facts as well?
Not in the same way, no. They are both very well supported theories of how, for example, species change or how traits get passed from one generation to the next.
But, for both, there are edge cases where the standard model doesn't work. neutral drift, for example, in population dynamics, or aspects of epigenetics for genetics. The theory is continually, well, evolving to meet the new facts and explain them.
