You kind of answered you're own question.
There is reality and there is perception.
Reality is.
We perceive.
G-d is everywhere. up up down down right left all around.
Since we humans occupy this little space called 'earth' we call are living space "down here" and we call G-d "up there."

Even if a prophet had a prophecy, asleep, in the comfort of his own bed, he would still refer to his message as coming from Heaven. In general when we refer to spiritual things we refer to them coming from heaven.

So even though G-d came "down" to Mt. Sinai to speak to Moses, we still consider the information to have come from heaven.

The last liberals the world ever saw were the Egyptians who sat Joseph's brothers down and fed them meat even though they despised meat eaters. Genuine liberals tolerate the opinions of others.

Today's faux liberals do not tolerate any other opinion and if one exists it has to be squashed.
