and prefers to stifle discussion by aggressive badmouthing.

I'm only bad-mouthing a fictitious God based on the crap in the bible in which he comes across as an idiot misbegotten bastard. As Richard Dawkins famously put it in The God Delusion:

"The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully."

Amen to that! Though I doubt the God of the New Testament is any better. Dawkins again:

"It's a horrible idea that God, this paragon of wisdom and knowledge, power, couldn't think of a better way to forgive us our sins than to come down to Earth in his alter ego as his son and have himself hideously tortured and executed so that he could forgive himself."

so, where is the evidence for your belief/hypothesis that there is no need for a creator ?

The evidence is EVERYWHERE and in EVERYTHING (excluding religious fiction, natch). God is in NONE OF IT. It is not belief, it is not hypothesis, it is simple commonplace beautiful joyful all inclusive objective natural REALITY.
