The predominant colour of the greys is highly indicative of the ‘greyness’ of humanity, as racial types begin to blend with one another so that racial types gradually disappear and submerge themselves into one common mass of deracinated and rootless cosmopolitan humanity. The aliens’ obsessive interest in genetics and hybrid babies also suggests that another agenda is at issue here, involving the racial engineering of mankind, again reflecting the direction that humanity is moving towards as globalism and multiracialism drives the motor. Are the greys showing us how we will progress and look like in the future?
