Amen, Cygnus! The existence of God cannot currently be proved in a lab, as others in this thread have already stated.
The method of discovery would need to change significantly to be able to discover God in a lab. Since that is highly unlikely it is highly unlikely a lab will ever prove the existence of God. Science may have already proven the existence of God. Even so, we would never know it. If a lab found such proof, history tells us that science would slap a label on whatever it discovered, describe its properties and attributes as best it can, and promptly declare it a part of reality that is "not God."
I have wondered for whom Rex toils, myself. He couldn't possibly believe he is aiding someone to a deeper spiritual understanding through his intense focus on fleshly things, could he? It won't work, if so.
I understand what he is doing if he feels a need to bolster his flagging confidence in the existence of God by attempting to prove such existence by use of a method that cannot be used to practically discover God, anyway. But it does seem a rather pointless exercise in futility. As does arguing with him about it. For a "man of God" he becomes abusive and peevish very quickly. In my opinion, he is not a very good spokesperson for his professed faith. Hey, maybe it makes him feel better about himself for preaching at the Godless.
