100% certainty is something many people are unsure of what it actually means. Are atheists 100% sure that god does not exist? No. No one can be sure that anything can 100% not exist (within the entire universe), the only thing we can do is have 100% certainty that something does exist. We are not 100% sure that there are unicorns with spider legs on the moon, its possible, but highly unlikely. We have never seen a unicorn with spider legs on the moon from our telescopes, so no we don’t believe it. But we can’t be 100% certain unless we inspect every square foot of the moon. But even after we do that, we still cannot conclude that the unicorns still do not exist on the moon, because 10 seconds after we make the claim, an alien spaceship could have come along and dropped the unicorn with spider legs on the moon without us knowing. It’s possible, but extremely unlikely, but still possible. The only thing we could be 100% certain of is that the unicorn 100% did not exist on the moon during the exact date and time that the moon was inspected.

The same goes for your own bedroom, you can inspect your entire room for god, every last square centremeter of it, and come to the conclusion that god absolutely 100% does not exist within your own bedroom. You now have “evidence”, that god does not exist in your room, but does this automatically become evidence for god’s existence outside of your room? Remember, you still don’t have that kind of evidence, you havn’t yet inspected outside of your room, so for you to believe it without any evidence would be defined as “faith”. The burden of proof, thus remains on you to provide the evidence. It’s not up to anyone else to provide evidence that something does not exist, it’s up to you to provide evidence that he does exist. It’s exactly the same as if I said, well there’s no Flying Spaghetti Monster within my bedroom, so he must 100% certainly exist somewhere outside my room. If you made a claim like this, people would think your mad! And so they should. Would you still then go around boasting, “haha you can’t prove the Flying Spaghetti Monster does not exist outside of my room, therefore that accounts for proof that he does exist.” However, you can see the point that I’m trying to make.
