In a way that is possible, practical, or reasonable for human beings to do; with human limitations in mind.
From 'human' (from Latin 'humanus') plus '-ly' (adverb suffix). Used since the 1500s to mean 'in a human manner' or 'within human possibility.'
The phrase 'as humanly possible' is interesting because it acknowledges our limits—if something is 'humanly possible,' it means it pushes us to our maximum but doesn't require superhuman powers.
