This sounds like one of those poll questions where, say, 50% of respondents say that XYZ should be outlawed, and then 50% of those respondents then admit they didn’t know what XYZ was in the first place.
I’m not surprised by the results, however. I live in a town where it is closer to 90% who do not “believe” in evolution, erroneously thinking it is an alternate belief system. Technically, however, the question should be whether people consider evolution to be or not to be valid, and why, which might yield a much different result. It is a valid concept, by the way, and does not disprove the possibility of God.
I would that evolutionists keep in mind that Adam and Eve are historically valid, but as the first domesticated slaves in the colonial-method transition from hunting-gathering to ranching-farming (including the literalism of nakedness, shame, perceived sin, poverty, humans cursed to work their own former paradise by landlords, etc). I consider this important to reflect on daily because it wasn’t voluntary (it was inevitable, but harsh for them nevertheless). I am an atheist who disbelieves in transcendent spirit but fervently believes in aesthetic/historical consciousness.
Some of the symbolism of Eden is literary, of course, but on the other hand, we don’t have the first Sumerian tablets that probably recorded several versions of it, which would have been either more literal or more pagan-myth oriented. Christians should note that like Genesis, the ancient Greek myths of creation, (the basis of our western literary naturalism), Chronos, mist, chaos, etc, are all featured as first principle at some point. This literal “symbolism” cannot then easily be used to render evolution as invalid, nor has any scripture declared evolution a false concept, nor has any scripture declared that all stories be taken at face value, nor is anti-symbolism even remotely a Christian concept.
