True, but mirages can be explained scientifically I think: "an optical illusion in which atmospheric refraction by a layer of hot air distorts or inverts reflections of distant objects" (wordnet.princeton.edu).
Thus mirages are explainable and induced by distortion of light due to atmospheric refraction. However, how does that make psychic phenomena any less credible? If you think it does, why stop at psychic phenomena? Why not doubt sense perception in general?
Considering sense perception is our only way of gathering information, you are basically denying the existence of any knowledge, including science.
