I confess that I started out with the presupposition that he did exist, because that seemed to fit the simple facts, but I've decided it was a mistake. He doesn't really exist.
True, I have communications purported to be from him. Those communications appear to be thoughtful, intelligent and kind, but that is misleading. In fact I'm sure there is a materialistic/naturalistic explanation for how these supposed communications came into being - I just don't know what it is yet.
But I am perfectly confident that given enough time, scientific analysis will come up with definitive answers about how these anomalies came into existence. Probably something to do with solar flares interrupting the electromagnetic field of the earth and creating random bits of binary data that organized themselves into apparently meaningful words through the Google spell checker with the complicity of some unknown redactor. It was bound to happen eventually by chance - and so it did.
As for the characterization of these communications as thoughtful, intelligent and kind - These are only the anthropomorphic projections of my own feelings onto these random bits of electronic jetsam. In fact they are meaningless and without significance except as an object of curiosity and scientific investigation.
Meanwhile I don't need to be at all concerned about Harmen's thoughts, feelings, values, etc. To believe in a real being named Harmen is just so much superstition - maybe even a form of mental illness (which I evidently don't have.) I don't expect to ever meet Harmen - since he doesn't exist. I can say what I want in any way I want - I'm not going to offend Harmen. (But I will be a bit careful because I don't want to cause too much offense to those who cling to their childish belief that Harmen DOES exist.) Nevertheless, I certainly should not let Harmen cramp my style. I'll do what I want and believe what I want regardless of what people think Harmen says. I'm not going to tiptoe around worried about what Harmen thinks.
I cannot have a relationship with an illusion like Harmen... but YOU can prentend he exists if it makes you feel good and makes you behave yourself. Harmen is a crutch you can lean on if you want, but I don't need such bandages for my thoroughly modern psyche. I don't believe in Harmen or in anyone like Harmen.
Now imagine how God feels about people deciding they don't believe in Him?
(Romans 1:18-23) ¶ For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness,
19 because what may be known of God is manifest in them, for God has shown it to them.
20 For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse,
21 because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened.
22 Professing to be wise, they became fools,
23 and changed the glory of the incorruptible God into an image made like corruptible man—and birds and four-footed animals and creeping things.
