Proof of what? You can't prove or disprove an unfalsifiable claim.
I imagined you could back up the claim if you were going to make it.
No scientist knows how quantum entanglement works, we don't know how light photosynthesizes in plants, but by some magic we're super-familiar with the macroscopic properties of planets enough to say they're dead rocks/gas?
The fact we don't know everything does not give anybody a free pass to just make up bullshit.
