    Do you think that there is vacuum in Earth's atmosphere? I think there is. Look at the diagram below:

    This is the molecular arrangement in gas, liquid and solid. We can say that the first jar represents the atmosphere of the Earth. If the air molecules in our atmosphere are arranged like this, there should be lots gap between them. What is there in this gap? If there is nothing in this gap, then there should be vacuum. So there should be vacuum in air.

    Yes, spaces between the molecules making up a gas is a vacuum.

    technically there is stuff even inside the best vacuum.

    It's your definition of vacuum that's causing this problem. We normally apply the term vacuum to a sufficiently large volume. It has no meaning when we get down to the range of molecular size. Adjusting the definition accordingly, there can be no vacuum in the atmosphere.
