I'm not to well read up on comparative religion. But yes other faiths do have their origins stories/Myth, and when i say myth, i don't say myth to mean a falsehood. Which is what most people associate the word myth with. But just in a general, to mean a story/account of what happened. Now all faiths, even to the pagan faiths, as i understand all have their telling of how the world came to be and, if someone else is more entrenched into this subject. Feel, free to chime in. But i'd say just look at the origin story and compare to that of Christianity, all the other faiths teach, either that the world is the result of a sex act of the Gods, An abortion, a mistake. Which, is interesting cause pagan myths tend to line up with evolution, that the world was just a Giant abortion/mistake. A good vid i found on this was Jay dyer, who actually goes into great depths, in this one podcast vid. A lot of stuff here, but also gives some interesting background information on other faiths, and their origin stories. Also, i think tolkien when in his discussions on myths, with C.S Lewis on myths in general. Was right on target with Christianity being the true myth. The Archetype that makes sense of the rest of them. Here's a short reenactment vid of the Tolkien, C.S lewis discussion https://youtu.be/NzBT39gx-TE. There's probably an article Tolkien wrote on it though. Which if he did, i'd like to find it and get a more in depth look. That's what started it for me, and i'm still in the process. I still have questions. But i'm more inclined to defend the Genesis accounts.
