But to put them all together in diverse creation tales ranging from Genesis to the Silmarilion... Also, keep in mind that a myth isn't always true... It's a lyrical way of expressing something we don't understand... maybe the genuine answer is simply boring.

Such hypotheses provide a solution to everything... The Creator(s) did it this way, so accept it but they don't tell you anything, such as that annoying bit about fossils What method did they use to get through the rock that was buried deep beneath... and seashells... I'm not sure
how they made it to the mountain tops.

Christians are quick to criticize other creation accounts, but not a literal interpretation of Genesis. For those who insist on following a literal Genesis creation, the explanation provided by Evolution is far more elegant.
