We get taller, in some nations, societies and peoples, but in others we don't. Could there be another factor? For example, could we be better nourished today than we once were? Could the size difference be just a standard variation provided by our genome? Such physical traits could easily be explained without evolution, and in fact, we find that the human genes aren't appreciably different worldwide, so despite the variance in physical size, it appears that the genes are the same. In short, we haven't evolved to be taller, we're simply expressing a variation in the given genome.
According to Occam's razor, the hypothesis with the least assumptions needed is the one that science should choose. Clearly, an evolutionary change to explain height (one that we can't see when examining the genes in various cultures) is a greater assumption than simply better nourishment and existing gene variation.
Nonetheless, if your faith is based in Evolution, good luck with that.
