True about DNA, opposite of what has been going on with God.<quoted text>
Yes, DNA was non-existent in their minds but it wasn't non-existent. It was invisible to their eyes but it was never invisible.
I think as we progress in the next few hundred years, God will become more & more less "invisible" and "non-existent".
First, we lived in an Earth centered universe, with the sun orbiting us,'cause "God" designed the universe around us. Next we get a heliocentric universe,'cause the Earth centered model was silly. Finally we acknowledge nothing of the sort. Then we lost our status as specially Created, having evolved just like any other animal. The Bible turns out to not be literally true; Genesis is so incorrect as to be ridiculous. The Flood is a crazy fair tale. Then our psyche is deconstructed; it turns out our minds rest solely in our brains and that dualism cannot be supported by the evidence we have.
Kicking and screaming, the church altered their positions. One by one, Christianity's monopoly over describing the universe around us falls apart. It now no longer contributes, is utterly voiceless, in the production of new knowledge and technology about the world. Science has forever wrested that from religion.
We're not describing a Created world. We've thrown open the curtains on that, cast light on the illusion, shredded it, my dear Riverside. History shows that your God is running out of room, losing His safety net as our primitive ignorance is replaced with evidence based knowledge.
Your God, like all those before Him, is a fiction, a fantasy. He doesn't exist and with growing education "poof!" bye-bye bronze age beliefs. We consign you to history, God.
