The reality of mythology isn't the reality of reality. God is only as real as Ra, Ea, El, Elohim, Allah, Apollo, Arjuna, Jupiter, Brahman, Marduk, Mithra, Theos, Zeus, Zoroaster, or any of a thousand others that superstition invented to explain phenomena for which there was no science.
Nor can anything be real which was fabricated from remnants of pre-exisiting myths, as God was.
The impossibility of God isn't a matter of physics. It's one of history.
God
Langan has described God as the global processor of the whole of reality, as the Primary Teleological Operator, the primary telor-syntactor, Global Operator-Definor, the SCSPL Global Operator-Designer, and as ultimately being identified with unbound telesis.
Quotes
"In keeping with its clear teleological import, the Telic Principle is not without what might be described as theological ramifications. For example, certain properties of the reflexive, self-contained language of reality – that it is syntactically self-distributed, self-reading, and coherently self-configuring and self-processing – respectively correspond to the traditional theological properties omnipresence, omniscience and omnipotence. While the kind of theology that this entails neither requires nor supports the intercession of any “supernatural” being external to the real universe itself, it does support the existence of a supraphysical being (the SCSPL global operator-designer) capable of bringing more to bear on localized physical contexts than meets the casual eye. And because the physical (directly observable) part of reality is logically inadequate to explain its own genesis, maintenance, evolution or consistency, it alone is incapable of properly containing the being in question."[1]
"Question: Or, alternatively, does God instantaneously or non-spatiotemporally— completely, consistently, and comprehensively—reconfigure and reconstitute reality’s info-cognitive objects and relations?
Answer: The GOD, or primary teleological operator, is self-distributed at points of conspansion. This means that SCSPL evolves through its coherent grammatical processors, which are themselves generated in a background-free way by one-to-many endomorphism. The teleo-grammatic functionality of these processors is simply a localized "internal extension" of this one-to-many endomorphism; in short, conspansive spacetime ensures consistency by atemporally embedding the future in the past. Where local structure conspansively mirrors global structure, and global distributed processing "carries" local processing, causal inconsistencies cannot arise; because the telic binding process occurs in a spacetime medium consisting of that which has already been bound, consistency is structurally enforced."
