if every proton in the universe is a monkeys that type random letters on a writing machine, you would have to wait 10^360 time the age of the universe until you have 1/10^500 chance that one happens to write hamlet by shakespear

now they say evolution works by random mutation and selection: some random mutation happens and you get an advantage for reproduction.

now the mechanism works for bacterias, its shown by statistic analysis of experiment (luria delbruck) but what about the odds at our scale? if that many monkeys cant ever write a book, what is the odd of getting an hear or an eye eventually out of randomness? Even if we consider intermediate steps.

Theres just not enough things happening and selection events in the world for it to make sense
