That would be wrong to think Heaven is on Earth, it is not and their is no biblical support for this position.
With respect to whats written in Heaven and earth is a misnomer.
The closes reference to what your suggesting is found in
Matthew 16:19
19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
Matthew 18:18-19
18 Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven.
19 Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
There are over 700 verses in the Bible on Heaven, none of them say Heaven is on Earth. Neither can we extrapolate Heaven is on Earth through any scripture.
The Matthew verses of binding on earth and Heaven, is to say that what happens in Heaven passes down to us on the Earth, not the other way around.
God said in Heaven let there be light and there was light on Earth. (Genesis 1:1–2) The binding refers to the works of the devil on earth against you. Since we are on earth speaking to God in Heaven and we are the ones asking God for something who is in Heaven, request from men start on earth and then its ratified or answered in Heaven by God, making the request real on the earth.
