If scientists look at a brain when it thinks, all they see is neurons being linked by an electrical signal. Is it such a leap to say that a conscious thought is an electromagnetic signal? There are four forces of nature. The strong and weak nuclear forces, gravity and the electromagnetic force. All are pervasive across the universe. The conscious thought that is running through your electric wires, to power your computer this moment, is beyond our imagination because it's not being created by a human brain. But it is still an electric signal, which is still an emergent consciousness.
