All kidding aside, what evidence of God have you seen? Do you ever think that the interruptions in your life are orchestrated to put you in the right place at the right time? Do you ever watch something in nature and think to yourself that someone MUST have created it? Do you stand in awe of the circle of life barely able to comprehend it? That's God. That's evidence of His existence.
Pay attention. Your testimony is the data. The data adds up. You just have to be willing to collect it.
For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
