Only believe what you can see?
That is actually a false dichotomy. There are many things that we believe in that we cannot see, such as love, justice, and the past. Also our senses can be deceived, so we cannot rely on them exclusively either. Consider this: Do you believe in love? Can you see love ? Do you believe in justice? Can you see justice? Do you believe in the past? Can you see the past? Do you believe in the Wind? Can you see the wind? If you believe in those things that you cannot see, why can you not also believe in God? We do not need to see something in order to believe in it, we just need to believe in the reasonableness of the evidence of it. God has already provided that evidence .
