"Therefore, atheist on this forum have asserted that God exists as an idea, but he has nothing to do with the universe, it's creations which includes man. That we are manifest from evolution. Is that right?"
Well, considering how we Atheists have seen a distinct lack of hard, solid, empirical peer reviewed evidence to the contrary from you lot, and to the satisfaction of we Atheists; also how now so many gaps have been filled, then the answer to your question is simple:
Yes.
Hey, you said it, I didn't. Kinda missed the point yourselves, when that telecommunications satellite your use of the internet is part of - which was conceived by Arthur C. Clarke - which you can't see, but exists [/Russell's Teapot*], nay, can be described, and is at a point way over your head, therefore...!
Not seeing any of said satellites containing components with the words 'Made by God' on them, so I guess we mere mortals such as the Atheist Arthur C. Clarke are superior to your 'God' then. And there are satellite-like probes such as Voyager that are only now entering deep space: the universe. Like I say: you said it, I didn't.
*- As per satellites/probes, can you say they don't physically exist, just because you can't see them? (One word: Rainbows): the idea of a Celestial Teapot as posited by Bertrand Russell. Question: Can you prove that said teapot doesn't exist? for if you can't, then your 'God' is less-than an 'idea'. Like I say: Rainbows. They don't actually physically exist, but when we can see them, then the 'idea' of the so-called 'Spiritual'/'Supernatural' has even less credibility than your 'God', when you can't even prove to the satisfaction of we Atheists that said Celestial Teapot doesn't exist. Are Rainbows a mere 'Idea'...?!
