People need to know the truth that God exists.
But that my friend isn't the truth is it. The world has been fed lies like this for thousands of years from false prophets like yourself.
The truth is, we simply don't know if god exists or not. Believing in god is just purely faith, nothing more. No words you say can change that.
You are simply projecting your ignorance.
To prove that all atheists (humanists) are mistaken, it is enough that I point to the observations which strongly support the survival hypothesis. This leaves only theism as a viable answer to the God-question.
