Ah, so now the issue is total independence, not just independence from God.
Interesting how the story evolves when you're challenged. (Incidentally, this is how confirmation bias coupled with cognitive dissonance works...you change the story to fit your worldview.)
So, Mankind could survive without God if Satan and his demons helped us out, is that what you're saying?
How about the parting of the Red Sea? Isn't that intervening in Mankind's affairs?
How about killing 180,000 Assyrians overnight...isn't that intervening?
How about every time God answers a prayer...isn't that intervening?
