The proof is there right in front of you, the cosmos is everywhere and we are part of that, simple, now to say there is a god out there that makes everything is going to take a hell of an imagination, an imagination you call faith.
Yes. The cosmos is everywhere (if you define 'cosmos' as 'everything everywhere,' which is a tad bit circular) and we are a part of that. How is that proof that there is no God Who may have created it?
BTW, "faith" is not 'imagination.' "Faith" is 'trust,' or the willingness to behave as if the thing you believe to be true is true. Some of us have more faith in our own beliefs and ideas than others.
I will repeat, however....no inability on the part of any human to prove that there is a God is proof that there is no god.
The obverse is true, too; no inability on the part of any non-believer to prove that God does not exist is proof that God does.
The existence, or non-existence, of deity must be arrived at personally, and by non-scientific means...for oneself.
What I see is that there is absolutely no difference between the passionate theist and the passionate atheist in one respect. Both the wordy theist and the mocking atheist are convinced that HIS notion regarding God is the one, the only, the TRUE, by golly, possible way to think about it, and anybody who doesn't agree with that idea is obviously stupid, or 'afraid of the truth,' or possessed by the spirit of Satan...or of mind numbed stupidity, depending on who's talking.
It makes me tired.
Here you are, doing the same thing. Yes, the cosmos is everywhere and we are a part of that. How does that PROVE that nothing, and no-one..or No-One..created it?
I have a pond in my back yard covered with lilypads. This year it has exploded with lilies. It has quite a few fish in it, too; some of 'em several years old and grown rather large, and a WHOLE bunch of teeny ones who get hatched...and then mostly eaten. Their world is their cosmos; self contained. I never feed them. The most I ever do is add water when required, and run the pump.
Now I'm sure that the fish, if they had brains enough to think about it, would consider their world to be 'the cosmos.' Everything in it works according to whatever laws apply. They have no ability to think beyond their cosmos, and no reason to do so. If some genius fish began to wonder why their water moves constantly in one direction, or why there are more mosquito larvae to eat at one season than at another, they MIGHT, if they were imaginative fish, figure that some Power outside their cosmos was in charge and made everything happen.
Or they might figure that their job wasn't to speculate about what...or who...caused the water flow, but simply to observe that flow and describe its effects; to eventually trace it back to its source, and finding it...and realizing that there isn't anything on the other SIDE of that source, name it the "Big Flood" and call it good. Which of those Einsteinian fish would be right?
The answer? Both of 'em, actually...because they would be investigating different things with different methods.
Your answer...and your 'proof' is amazingly religious, y'know, almost fanatically so. Indeed, your notion that the Cosmos (including us) is God is a well known religious idea. Unitarians come close to codifying it, in a way.
But you haven't proven it.
