You're assuming that the information about a) Adam and b) how long he lived for, is accurate.
No, that is what a literalist does. Adam isn't a historical person who lived at all. Instead, you have a metaphor for all of mankind, and that's Adam. His lifetime reduces to 12 and then 3, which is interesting happenstance relating to a few weird things and nothing more.
Any actual evidence?
Of occultist ideas in the Bible? Have you read Revelation?
Right - so basically this is all a guess.
More of an inference, and I'm not dogmatic about it. I can't tell, are you upset? Because this is not the subject to get bent out of shape over.
