Answer: No.
Some people say God cannot be omnipresent (not present everywhere) because how can God be in dirt?
Although Lord Krishna (God) is present everywhere, the source of everything, and everything is His energy. He is aloof from all His material creations. He is not affected by His material creations. This is the inconceivable opulence of Lord Krishna. This is how great Lord Krishna (God) is.
“..Although I am everywhere, I am not part of this cosmic manifestation, for My self is the very source of creation.” (Lord Krishna, Bhagavad-Gita 9.5)
The sky is everywhere, but it does not mix with anything. In a similar way, Lord Krishna is present everywhere but He does not mix with anything.
“The sky, due to its subtle nature, does not mix with anything, although it is all-pervading.” (Lord Krishna, Bhagavad-Gita 13.33)
The air enters into water, mud, stool and other filth, but still it does not mix with anything. In a similar way, Lord Krishna is present in water, mud, stool, but He does not mix with them. He is aloof from them.
The sunshine is everywhere but it is not attached to anything. In a similar way, Lord Krishna is everywhere but He is not attached to anything.
The wind is blowing everywhere but the aromas it passes through do not affect it. In a similar way, Lord Krishna is everywhere but He is not affected by anything.
