See my above post for why your argument fails on a biological level, but it fails on a theological level as well.
Most Christians believe in the trinity (Catholics, Orthodox, the established churches):
“And in one Lord Jesus Christ, the
only-begotten Son of God,** begotten of the Father** before all worlds (æons), Light of Light, very
God of very God,
begotten, not made, being
of one substance with the Father;”
From a theological perspective, Jesus shares one being with the Father, he is begotten,ergo not a separate species.
So, in order for you to prove your point, you not only have to:
- Prove that Jesus had a unique brain
- Prove that part of his brain was developed for the sole purpose of serving the Father
- Prove that God was a different species
This would run contrary to the beliefs of pretty much everyone in the world (Christians, Jews, Muslims, and atheists for a start) who disagree with you for various and different reasons.
