Atheists:could you imagine that?

If the two explanations were indeed 'completely opposite', I find it difficult to imagine that both would appear convincing. Too many things would have to be reversed.

However, if you allow the two explanations to be fairly similar, yet not precisely the same, then I would say it probably is possible. But you would still have to limit me to reading only one or the other of them. If I read both, and recognized the differences, I would of course have to come to a conclusion as to which one (if either) was accurate, and tentatively reject the other.

Wrong section, you should ask this in the cosmology or biology section of Science.

No need for imagination or a computer. Such documents, written by real, live people actually exist.

There are currently a handful of plausible scientific hypothesis about the origins of life which have not, through scientific experiment, shown to be impossible. So, if you define "belief" to mean "accept as possible and not yet proven wrong" then quite a number of people would believe opposing hypothesis about the origins of life.

That's the great thing about science based belief. You can believe that several scenarios are possible without committing to any one and you can change your beliefs as more evidence comes forward.

only if what i read was verifiable.

though i dont see how i'd verify "Donald Fauntleroy Duck" as realistic, and everyone already knows what utter crap the bible and quran are, so no.
