I think a good analogy to use on this is to compare the way video game technology has advanced in 40 years. 40 years ago we had Pong, now we're entering a current technology where thousands of players at a time can play photo realistic virtual simulations with each other. If we continue by this type of progress within a few more decades the simulations or games we're playing will be hard to distinguish from real experiences.

If technology can be used as this real analogy, are we currently in a simulation /game and the spirit world is the more real and base reality? Or is this physical human world our base reality and the spirit world is just a temporary place of planning until we come back again into another physical life?
