Uncle Ben, the man who raised Peter from birth with his wife May, and who taught Peter the lesson that inspires him to be a hero, who is the base for the iconic phrase "with great power, comes great responsibility" hasn't been seen in the MCU. Tom Holland's Spider Man has been in five movies so far. We've seen Aunt May and Tony Stark works as a father/mentor figure for him. As far as I remember, there has been no indication about Uncle Ben so far.
So that makes me wonder... Does Uncle Ben exist in the MCU? If so, in what condition? Is he dead as usual or alive somehow or something completely different than above two?
