ha..ha..ha.. we have to answer to your misintrepratations. it is true God is everywhere. why we say God is everywhere ? it is also true that we made image and we installed it in a sacred place for worship. God is everywhere means, you need not go to the particular sacred place to think of Him, to pray Him. you can do this where you are.
if you are in a bus, or train, or plane, you can think, you can pray. it means the God is in bus, train and plane. why are you crying when bus runs fast ''oh! God save me''..in this scene, will you go to the image of the God in sacred place to request him to save you ?
if you happen to see anything unnatural, or unexpected you express your astonishment or fear saying ''oh! God''. This also means that God is everywhere.
why you go to hospital and pray ? Have no belief on doctors ? is God there in hospitals ? if you need more proofs, i can say. you are saved from an accident, why you say ''oh! God, thank you''. you think you are escaped by your presence of mind. That is not true. The presence of mind will workout not all the time and only in some time. Here, because of your past karmas and having God's blessings, you are saved.
God is everywhere means, the God is sitting as a soul with everyone. so, you can call God 24x7. He is everywhere. He is kind. He is here to guide us. if you put this in mind, you can understand the God is everywhere.
i hope you understand this at least now.
