As this thread shows, the "true meaning" could be anything!
i have to rate "aliens in the bible" a half-point less than "moses's cd-rom collection" on the wackiness scale. for some reason, aliens are just slightly more plausible than time travellers from 1994 with a 386.
As long as there is some hint of meaning in the text anyone can interpret it to mean whatever they want.
well, hang on there. some interpretations are, indeed, wrong. we CAN'T simply interpret it to mean anything we want. people TRY.
So, I see your point to jar, but I would question the larger point of applying any kind of validity to whatever zany interpretation one can come up with (using canonical evidence). Yes, NotQuiteEvolvedRudeRacistGuy can believe that the Bible describes ET and spaceships and IMHO that has just as much evidentiary basis as the rest of the claptrap in the bible.
well, hang on there too. there's a lot of myth and racism and general goofiness in the bible, yes. but there's other stuff, too. the book of kings is pretty reliable as a history text, even if it omits some choice things. and the exile does seem to have really happened.
