I remember reading once that, due to earth being much smaller than the majority of observable rocky worlds (but still within the tolerance to retain atmosphere and within the goldilocks zone), that our low gravity has probably put humans in the 'large' category of alien fauna in the universe. At least we have that.

So maybe the aliens already visited us, and were swatted as mosquitoes.
