Theist's- can you PROVE that there is NO monster under the bed?

nice i just asked this question! except different wording but still! :) they don't think that they need proof, then they ask you for proof, and go on to something else, thinking they are right your wrong, blah blah blah it's the same answer... i don't know why they look under the religious section anyways, just to prove that they are right? who knows i think this should be for Christians although it's a free country so yea! God Bless
