Re: "How did God create a female (Eve) from the male DNA of Adam's rib?"
Simply put, goodbye Y-chromosome, hello duplication of X-chromosome.
Re: "How did Adam and Eve successfully mate and produce offspring when, at most, they had identical DNA, and at least, they were twins?"
I do not find it entirely improbable that Adam and Eve could have had very different DNA, if God had chosen to create an entirely new set of DNA for Eve instead of using Adam's.
Re: "How did a snake acquire the ability to speak in human language?"
Several explanations have been proposed. One is that, before the Fall, some animals, such as snakes, actually possessed great enough intelligence and the ability to talk, and that such features were removed in the Curse. Another proposal is that the serpent, controlled by Satan, was not itself the agent of the speech, but rather that Satan, controlling the serpent, spoke, either nonverbally in direct communication to the mind or verbally.
Re: "Stipulating that, how did Moses and the Israelites pass through it? After all, it was substantial enough to deluge Pharaoh's army."
Re: "If the sea was parted, how precisely was that done?"
Short answer, miracle. Long answer, through some supernaturally generated force that restrained each individual molecule of H2O away from a given area, the area being the path traveled by the Israelites.
Re: "How did Jesus rise from the dead, and walk around good as new, when after three days of death he would be brain dead, with decayed muscles, bloated from gasses, with blisters on his skin and with millions of dead and useless cells, including dead and useless heart and kidney cells?"
The cells spontaneously begin functioning once again, synapses in the brain recommence firing, etc. The decay processes reverse instantly.
Yikes, that is a lot at once! Wouldn't be so bad one-at-a-time (in fact, it's a lot of fun! ), but all at once...
I remember evolution in biology last year... nearly every kid in the advanced class happened to be a creationist... and the top ranks of the advanced class were the most vocal. We tried to debate the teacher a bit, and we raised a minor fuss. All of a sudden, we "didn't have time" to cover the real evolution chapter. It was sort of anticlimactic. ...we spent the last few weeks of school that year watching random movies in science class.
We're working on Greek mythology in English class a bit now. (The Iliad, Oedipus Rex, Medea, and the like, mostly, with some background info thrown in.) It's taught by our student teacher. As he phrased it, he is "lucky" to have me in the class (though I torment him here and there and occasionally embarass him ) because I was really into mythology as a kid and I remember some things.
