The difference between Science and Religion is not proof, because nothing is ever really proved in Science. The difference is that for Science there are clear criteria for dis-proof. A science fact is a fact not because we proved it but because we have repeatedly failed to disprove it.

So if there is an answer to the question what would it take for you to disbelieve in X. its Scientific if there is no answer it is religion

There is an answer to the question: what would it take for you to stop believing in the 1st law of thermodynamics? Everyone pretty much agrees what it would take and it has never happened.

So to thw case in point. What would it take for someone to disbileve that we are in a simulation. Answer Nothing because you can always assume a more complex simulation. Ergo it falls in the realm of religion.
