How is one orgins story considered better than another

[Silver]

Be honest with yourself and acknoweledge that It all boils down to you pointing to a guy or a group of people who you believe to be credible because they are smarter than you, and what they think. And for them what they think is based on what someone smarter than them thinks, and so on goes the daisy chain.

Certainly, the ideas of others, mainly the brilliant Robert Green Ingersoll, set me on the path of understanding that it is illogical to believe in something for which there is no evidence to support its existence, but in the end I arrived at that reasonable conclusion not because others believed it but because my own thought processes, along with better than average reading and critical thinking skills, allowed me to reach the knowledgeable understanding that faith is absolutely useless.

Why shouldn't both accounts be taught side by side

I am certain it has already been stated, but there is no harm in reiterating something important. Anything in relation to religion and faith should not be taught alongside science for the simple reason that religion is utter bullshit.
