Sorry, no. For the umpteenth time: evolution has nothing to do with the beginning of life. That's abiogenesis, silly, and it's only a hypothesis yet, as no-one has been able to recreate beginning of life so far. But they have a good idea of how it was done. The Bible has no how, at all.
If there is no scientific, provable evidence supporting it, there is no theory, you stupid bint! Evolution has it in droves, as it has passed the Scientific Method, and became a Scientific Theory.
The ToE has evolved so much since Darwin's day, he would hardly recognize it any longer. You fail so hard, you're not even wrong. There is literally mountains of evidence for the ToE, in thousands of museums around the world, inside our own bodies and the bodies of all other forms of life on Earth, and in remains from former forms of life, still interred in the ground.
The Bible's creation contradicts itself, and it has no evidence whatsoever outside the Bible.
The authors of what? The Bible? They had very few facts, that's for sure!
School boards have access to all the facts, if they want them, as they can easily be found in scientific journals.
Creationists were given the chance to present their evidence, and henceforth be included in scientific education, in the Kitzmiller vs Dover trial in 2005. They didn't manage to present any kind of evidence, hypotheses, ideas, anything, and were subsequently laughed out of court. THAT is why no alternative is taught; There. Is. No. Alternative.
