Yes. But that is the beginning. That is a mere ‘quantum’ of what ‘is’ and what there is yet to discover/learn/know.
It is, IMO, delusional for a people confined to their planet/solar system (and Voyager is one little highly limited exception) to think they can definitively say SQUAT about this particular issue. That is stupid arrogance.
I believe God wants us to be curious about His existence, both within the universe, and even outside of space and time. That’s what makes M-Theory so interesting.
Held together by the consistency of math and physics, these things give us ever more interesting takes on being made “in His image”.
IMHO, anyway.
