It is quite possible for man to create accurate complexity within a very brief moment, for him time and space is not required and it takes "blink of an eye" to decide that you are the one and imagines marrying you, having kids with you and growing old with you. After all it took split of a second after the Big Bang for energy to shatter in to distinct forces creating matter, protons, electrons and so the universe was born. All of this happened within a second.
