Has that ever not been the case? God has been the goto explanation of anything modern humans didn't understand.
The most brilliant minds at various points couldn't have thought "aye, if we cut a tiny thing inside a metal heavier than lead or glue these tiny things inside air it can create more energy than lighting/gunpowder/dynamite".
Or that wireless communication is possible and sending a manmade moon out around the Earth is also possible, and you can do both for instantly sending light signals, nay, whole books around the globe.
Or virtual worlds that are not bound by any physics (maybe we're dumped into one at birth which can make any observations rather pointless heh).
I can't imagine FTL (although far out theories exist), but our current method of choice is chemical explosions, so there's some massive improvements to be made there.
But we currently have absolutely no evidence nor hints that might happen. We actually have more indication that an almighty creator exists than we have indication that humans may someday achieve FTL travel. At least the former has eye-witness testimony spanning hundreds of documented cases across centuries and cultures. FTL travel? Just speculation and Gene Roddenberry.
