The evidence is all around you in nature. While nature itself tends toward disorder and deterioration, there exists a universe that works on scales grand and microscopic. Left to its own devices, it is easy to see, nature would rot and stray and fall apart. That it does not suggests that there is something behind it that we do not see. That is not iron-clad proof of God, but it is evidence ... whether you accept it or not.

The evidence also exists within me. Whether or not you accept my experience as valid, I have a relationship with God through my Savior Jesus Christ. He speaks to me through the Bible, through other believers and through nature. I know that to be true because I have lived it for almost 40 years.

You don't have to accept that evidence. You are allowed to be wrong. There are consequences for that sort of arrogance, but since you don't believe in God anyway, you believe you won't mind spending eternity without Him. You're wrong about that as well and will regret it.
