"Is outside time and space" is the same as "is not". So I think you have it right. Put "God" as the first word in the two phrases I just quoted. See? ?

A wormhole exists outside of spacetime and is interdimensional..

Existing outside time and space is IMO unimaginable.

Wow, I loved this, just loved this and I shall use it myself, Thank you

It is the same as saying that God has always existed and that He exists outside of the space-time continuum of our universe, but not that He exists in nonexistence.

Well some theorize that the Universe is "ballooning" or creating mutli-verses. Anything outside of this expanding universe.. is still some kind of matter..though we don't know what.. ? So, what would be outside of the expanding Universe? It's beyond me and my understanding to know how God could always exist.or come into "being" at some point. I guess that is why so many of us agree that there is no god.
Is time related to the observer?

I like that one!

How can anything exist outside of space and time? Can we even comprehend that scenario? If there is no space and "time", is there anything? Is there such a thing as non-existence in terms of universally?

When they specify what they mean by 'God', 'time' and 'space'. we can start a discussion. Until then it's just a word-salad that doesn't merit my time.

Gods god is outside of eternity.

Taken literally, I suppose some of these comments are pretty much on the money. However, the phrase is not used as a literal statement, but as a way of saying 'not constrained by' time or physical space. If you attempt to use the 'argument' as presented, you will be slammed to the mat and counted out in a big hurry. It sounds clever on the face of it, but in fact it is not.

We already know that debating with the masters of animated goalposts is an impossible chore, even with solid positions based in real logic, so why go in with a guaranteed loser?

As for the theists god bit it just another bit of bullshit they can't explain and can't justify so is meaningless.

But on the actual question of existing outside of time and space. There are some parameters which would influence an answer but wouldn't it be another dimension because that would be outside our time and space but not necessarily there own?

I await the deluge of intellectual stuff with baited breathe lol

as soon as time/space can be know none can answer what outside of either are as both time/space move

"What would being outside time and space be?"

I had to read this one repeatedly to make sure--I think at least--I understood the question. Just say it out loud, and see if it isn't a little tricky!

That said, we might as well ask, 'What would being outside the laws of nature be?' The simple answer is either 'nothingness' or 'supernatural.' And yet, what if there is existence outside our understanding of the universe? What if there exists a domain beyond our definition of space-time? Would not such a discovery be an expansion of our knowledge of the natural? What then is left for this myth we label 'God?'

Given that existence is defined as being able to be perceived as occupying space and moving through time, a being outside of time and space could have no motion and therefore could not be perceived as possessing any of the traits of existence, and therefore cannot exist.
I can only conclude therefore the contention "God exists outside time and space" to be a Self-refuting statement.
