Re ransom claim: For one, Jesus should have been required to deliver proof that he was the "second Adam" by living, with the available angelic protection he claimed existed, naturally past the age of the first man. say, to a ripe, but young 10001 years. The light of the world, like photons, that do not age, ever.
then he would be the proven, believable equivalent. To live a life of sacrifice; not just a 3 day/nights sleep at a normal average life span age, of that era.
