Do all theists use God to justify everything they know nothing about?

I wouldn't say all, just things that nobody truly knows, like why we're here and how exactly it all came to existence.

But I am willing to say anyone who denies evolution or the Big bang, does this. And anyone who says "Why do you think you wake up everyday?" or "How do you think the clouds got there?"

Things that have scientific explanations. I do think a vast majority are willing to attribute things they don't know to God because it's a cop out.

That's the whole reason God was made up in the first place.

Your question makes absolutely no sense at all. Why would atheists use god when they don't believe in god. A atheist reasons with science why the sky is blue. Not because god makes it that way.

God only knows!

Only God knows the answer to that. [sarcastic grin]

Imaginary gods do not and cannot justify anything they never leave the mind that imagined them!!!

Although I am a Pantheist, I love science. If I do not know something, i'll admit it.

Not all, but many, just as many atheists do using their negation of gods.

what about u guys know about .. u cant study other religions and theories(if u did it makes your bilefes week) .. u r against with science .. u ppl r blinded buy your own religion ..

If you remove the extremes from that statement, yes.

Not all, not everything, and not nothing.
