【Show】 ,  【manifest】 ,  【evidence】 ,  【evince】 ,  【demonstrate】  are comparable when they mean to reveal something outwardly by or as if by a sign or to serve to make something outwardly apparent or visible.

【Show】 implies enabling others to see, but in this case what is revealed can only be inferred (as from acts, words, or looks).

【Manifest】  implies a fuller, plainer, and more indubitable revelation than  【show】 .

【Evidence】  is often used in place of  【show】 , but it specifically implies that the outward act or utterance serves as proof of the existence or the actuality of something not fully proved or in question.

【Evince】 implies some outward marks or tokens (as of an interest, an emotion, or a power).

【Demonstrate】  (see also PROVE 1 ) is used chiefly in reference to feelings; it ordinarily implies obvious or even deliberately displayed external signs (as effusiveness, enthusiasm, emotional excitement, or significant actions).
