You appear to be moving the goalposts. These are all concepts. God is not as real as Money or Love or America. You’re conflating several things here to try and obfuscate that the existence of God being proven isn’t a “big deal”.

If something is real, it can be proven, observed, the effects replicated. This is how every thing in the universe works. No exceptions.

Money can be proven, even the idea of it, even though it’s “conceptual”. It has real value, it’s a construct we created and it has physical objects in the real world and can be exchanged for goods and services. It’s a real idea that takes physical shape in the world and it can be proven as a real world concept.

Love is a concept, and while the nuances behind it aren’t well understood, it’s as real as anything anyone feels, like hate, fear, or any emotion. It’s an emotion, and emotions are a part of the human empathic experience. It’s something we’ve evolved and learned over time. It’s real because we make it real every day. Love isn’t existential, it doesn’t have some power we’re unable to measure. It can’t bend or warp or shift reality. It can’t do anything more than we can do as a human. In all the ways that matter, any result of love is 100% measurable and observable in the physical world.

America is a real place, a real continent, a real country, with real people, and while the idea of a country or its people changes over time, it’s not “fake” or made up, in the same way a claim about a deity is. The idea of America might be what you’re referring to, but it’s as real as any other shared idea or dream people have had in history, including Rome, the EU, etc.

You’re intentionally trying to muddy the waters and misdirect here by conflating the “realness” of God with 3 things that are nothing like the claim of God, and that can be quite easily proven with objective evidence.

Anything anyone claims that exists outside of our ability to observe, test, or measure, is either talking about things so small or far away that we haven’t developed the tools to measure and observe them yet, or they’re spouting bullshit.

Which bucket do the claims of god, and all religions fall into do you think?
