Tommy goes back in time to cut his hands in elementary school. But through the eyes of his prison cell mate, his hands will already be scared when he first set eyes upon Tommy. Therefore, no miracle would be proven.*

This leads to another flaw. Tommy did't started his diary until after school incident. So how could he have notes written during the occurrence?
