I don’t agree with everything in this video, particularly about the denominations objection, but it’s otherwise a pretty good apologetics scattershot of atheist objections.
Obviously any single objection would require more than a 10 minute meme video to really explain.
0:38 is wrong, it’s entirely possible to go through life without a metanarrative, and is a much happier way to live.
That’s just your metanarrative.
