Uh, hello, I'm applying the Christian point to the matter. Outside of God, I totally agree with you.
People don't have to believe in God if they don't want to, such as you. A society doesn't need a religion to survive. That's obviously true.
As for government, I don't think you're 100% correct there. Yeah, you could theoretically have no government for your people (though that is technically anarchy), but then you'd have no unification, nothing to stop you from dying, from getting murdered, from getting conquered by another government.
Sure, you don't "need" a government, but it's certainly not a bad thing.
You think you can shut me down by dissing my belief? You should know that that will only get a person started.
I don't have evidence? You have no idea how much evidence I have. Miracles, fine tuning (teleological argument), deductive reasoning (kalam cosmological argument), historical proofs, etc.
