To falsify the omnipresence of God, one need only demonstrate that God does not exist in at least one place.

Genesis 3:8 And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden.

Genesis 4:16 And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.

Job 1:12 And the LORD said unto Satan, Behold, all that he hath is in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the LORD.
