all I am saying is that an omnipotent God (if he exists) can create gravity (and other constants)
You said more than that. You wrote, "In the case of God, there are many things that have no explanation , that that could be explained if God exists. … (the fine tuning of the universe would be an example)" I asked why an omnipotent God would need to fine tune a universe. I argued that the very concept implies that God is constrained to set the constants of the universe according to rules that transcend its power, just like man.
Nobody is claiming that God is constrained to create those laws
Anybody who claims that the universe requires fine tuning is claiming that nature could not contain stable galaxies of solar systems containing conscious life had the physical constants been slightly different. It's an answer to the anthropic principle, which asks what kind of universe would you expect self-aware intelligent life to arise in? It asks how such a universe could exist if its existence is extremely unlikely. The answers have to be either that there is no fine tuning problem, universes are not created finely tuned but instead evolve under some pressure to become finely tuned just as matter is not initially finely tuned to be living but instead naturally tends toward that state, that there was an intelligent designer, or that there was a multiverse capable of generating all possible universes in copious supply like the stars in the sky and it was inevitable that some would be finely tuned for life and mind without an intelligent designer.
I haven have seen such refutations.
Here's a summary of several of the classical arguments for God:
Understanding (and Refuting) the Arguments for God - Big Think
“if there is a multiverse, each universe with its own “values” then the vas majority of observers would be Boltzmann brains.”
I don't know why you put that in quotes. It look like it's your words. Furthermore, it's not a valid argument. The conclusion doesn't follow from what preceded it (non sequitur). There is nothing there that prevents a multiverse from existing, or from producing a universe just like this one.
many atheist form this forum could learn much from you
Thank you, but they seem to be doing pretty much the same I am.
Judging by your avatar, it looks like you're a Pinky and the Brain fan. If so, you might enjoy seeing these collected together.
Brain: Are you pondering what I'm pondering?
Pinky: "Sure, Brain, but how are we going to find chaps our size?
"I think so, Brain, but this time you put the trousers on the chimp.
"I think so, Brain, but where will we find a duck and a hose at this hour?
"Well I think so, Brain, but if we didn't have ears, we'd look like weasels.
"Well, I think so, Brain, but where do you stick the feather and call it macaroni?"
"I think so, Brain, but burlap chafes me so."
"I think so, Brain, but me and Pippi Longstocking... I mean, what would the children look like?"
"I think so, Brain, but this time, you wear the tutu."
"I think so, Brain, but isn't Regis Philbin already married?"
"Uh... yeah, Brain, but where are we going to find rubber pants our size?"
"I think so, Brain, but culottes have a tendency to ride up so."
"I think so, but where will we find an open tattoo parlor at this time of night?"
"I think so, Brain, but if they called them sad meals, kids wouldn't buy them."
"Uh, I think so, Brain, but we'll never get a monkey to use dental floss."
"Well, I think so, Brain, but I can't memorize a whole opera in Yiddish."
