How can one establish the existence of unimaginable God?

Question: How can you establish the existence of the unimaginable item? You can say that something exists only if you come to know about it. When you do not know about it, how can you say that it exists?

Answer: In this world several miracles happen. The miracle is unimaginable but still it exists. The boundary of this Universe is also unimaginable, but it must exist. Therefore, the proof of the existence of unimaginable item exists in this world. In fact to give the proof of the existence of unimaginable nature, God created this unlimited Universe with unimaginable boundary. The same God shows various miracles in this world so that the existence of unimaginable nature is established; thereby the existence of unimaginable God is also established by the extension of the concept.
