Evidence comes in many forms. It can be hard, physical evidence, such as a video of a thing happening, it can be circumstantial in nature or it can come from personal testimony. When you see God it's too late. You will have your evidence as you stand trial for rejecting His grace. So what evidence do we have of God? There's plenty on this website. There are several threads about miracles, which you can search. There you will find average people who have experienced extraordinary things retelling their encounters. The thing about pretending there is no God is that you have to pretend we live in a purely natural, physical word. A single supernatural encounter disproves that. Dare you seek the evidence, or will you sit in blissful ignorance pretending that actions have no consequence.
