Re: Did Jesus hang on the cross millions of years ago?.....His works had already been FINISHED since BEFORE the foundation of the earth.
There have been 'worlds'/realities/strongholds on earth before us (six extinctions) that, since we cannot (or will not) explain properly, scientists find it convenient to 'classify'/CATEGORIZE (slight of hand nomenclature/terminology) as 'species', etc. (homo sapian, neandrethal, etc.)....,..were the Jews/Hebrews NEANDRETHAL, nephilim, etc.?.
SOME missing planes might have come into contact with TIME PORTALS and have returned decades later (sometimes with DEAD passengers or passengers that were aged)....

Judaism might actually be what the Hebrews never overcame in order that they would be able to MOVE ON (adapt) to THE CHRIST (since Jesus" works had been FINISHED but not yet revealed).....this is what Hebrews 6:1 tells us to do ("MOVE ON" from the INTRODUCTORY/elementary doctrine about :"THE CHRIST" (so that we will no longer have a faith TOWARD CHRIST but be IN HIM).....it seems the Jews never moved on because they were always playing with PAGANISM.
Very often, SCI-FI illustrates more clearly spiritual principles about life...(is the spiritual realm NOT better understood as "fictional" science?)....
