The reality is that none of them make any more sense than the other, none are unbelievable, none are plausible, none serve to verify the existence of a thing we've convinced ourselves our entire lives to believe in.
Regardless of your faith, logic, ability to analyze or think critically, there remains a single unifying fact among all life on the planet and perhaps the universe: we don't know, and probably never will. Do you want to be indulged in the secret to happiness, inner zen and tranquility with your logical and spiritual side? Repeat to yourself "I don't know the unknown, and that's okay". No scientist knows, no magical entity or divine spirit resides within reality who will teach us.
You need to accept that seeking non-existent answers to the same question billions of people ponder every day will only drive you frustrated and hopeless. All of us, regardless of our beliefs or where we come from, are heading towards the same inevitability, there is no point in questioning it or debating it.
Find peace and happiness in knowing we are all equally as clueless as the next, and you may as well be living in a simulation where nothing truly matters when the end result is always the same. You'll find relationships easier, anthropology easier to comprehend, and your charisma will hugely improve.
