It's much harder to prove the non-existence of something than the existence.

Just show the concept either is not where it is claimed to be or that it is incoherent.

I say this as someone who believes in a higher being, we have played this game before, the ethereal thing can just move to someplace science can’t get to, it is not really a valid argument for existence.

what argument?

The question wasn't about which is harder, it was asking for proof.
