Sure, physical cosmology is science, not maths or philosophy, so logical deductions based on observations are the standard. In this case, if an expanding universe gives you a perfect prediction of the shape of the cosmic microwave background through the Sachs Wolfe-Effects, and the alternate hypothesis of mere galactic movement has no way of predicting this or to even accomodate it without completely fudging it, it's basic scientific reasoning that hypothesis 2 is basically dead for the time being.
