Look into the physical evidence of cuneiform tablets about crosses and sacrifices made to make way for a vision of prophecy, an oracle. That is the very meaning of the ancient symbol of a cross used since 3500 BC up until less ancient times. There are physical tablets which when deciphered provide evidence of this. That cross and blood of Christ made way for the Holy Spirit and prophesy which followed. God who provided this is seen in it. It is evidence of God. You merely need to understand and know. You can find it in secular sources on the internet.
