Fun fact: this is how they separate oxygen, nitrogen, and argon from air. You cool it to a liquid, and the. Slowly heat it back up. Nitrogen boils off first around 77K, then Argon around 83K, then Oxygen at 90K.
I find this so cool, even though it's like "oh yeah. Just like distilling alcohol or petroleum"... But... Like super cold...
We can also prove its existence scientifically. We can detect by testing for it. We can chemically react it with other elements. There are lots of things we can't see with our eyes but we know exist through scientific study.
So far no test for god has been developed. We just have an old book that claims bats are birds to go by.
The funny thing is that we actually see oxygen, but as a gas it's so dispersed that it's almost fully transparent.
In theory, if you could press enough air into a tight enough volume (like, say, 1 cubic meter of air into a 1 cubic centimeter), you'd get a similar result.
There is still sin in the world, but there are no ice giants.
You best put your finest Viking helmet on and bow down in worship. Not the one with horns either because that's not historically accurate and Odin will absolutely smite you for that.
I feel like it's quite the strawman or misunderstanding when people ask for material proof of God. Can you prove math using empirical verification? No. because math is not something you can empirically verify as it does not exist materially.
