What are your positions on the arguments for God? This simply is not true. The Bible says God visited Mount Sinai and helped Moses write the commandment tablets. Moses asked if he could see God's face, and God said no because the man would die, but he allowed him to see or feel his hand pass over.
Also in that instance, God could be seen by the masses descending onto the mountain as a giant fiery cloud making noise with lights flashing around it.
God's voice walked with Adam and Eve in the Garden of Eden, and a voice requires physicality.
Jacob wrestled with God in the desert and said "I have seen the face of God and lived". Many Christians would argue that this was an angel or Jesus, but that's not what the book says and is speculation.
Jesus was God in human form, and the 3 aspects of God are inseparable. The Christians who argue that this is not true are a very, very small minority.
These are just a few examples.
Also...heaven is ascribed earthly measurements and qualities which are physical. It's like a giant cube with streets of gold, etc. Also...the new Jerusalem exists on Earth after God destroys the world, and this is where God resides in person forever with the chosen 144,000 Jews.
