Complex systems always develop from simpler systems, not from things that are more complex.
The claim that an infinitely complex entity (which supposedly always existed) made humans from dirt is exceedingly more unlikely than the gradual progression of subatomic to atomic reactions, simple chemical reactions to more complex reactions, and simple organisms into more complex organisms.
Creation was always a poor explanation, but in the presence of knowledge, belief in creative acts by magic sky gods is indefensible.
It is quite irrelevant whether it would be 'better' or 'nicer' if things were made by a happy sky friend, because it simply isn't the case.
