"I think...From what I heard, flies aren't actually aerodynamic, and they are only good at flying because of the speed of their wings."

Flies also weight less than 1Kg. Humans weight about 54-64kg (female) or 76-83kg (male) on average. And we have (obviously) significantly bigger volume and mass.

Note even animals capable of flight have difficulty among their bigger species. Big birds of prey don't actually fly as much as glide, in contrast to smaller birds like doves, and it's much harder, if not impossible, for them to actually take flight easily from the ground (they throw themselves from tall places to avoid that problem).
