For all those who immediately look at this and jump to the conclusion that it's stupidity, I think you're misunderstanding OP (you may not, but a lot of you probably are.)
It's not meant as a literal ehow tutorial on how to make God's existence evident. He's saying,
despite what you believe, why don't you go and just try out praying or going to a church or something like that. What happens may be surprising, and may even alter your beliefs. In fact that's how most conversions to and from a religion happen, by experience, not by some useless debate or conversation online or by studying evidence. Whether or not it's intended, if you just study up on something alone or have a debate online or irl you're going to end up having a biased view in some way or another. Let's just say that something does happen- a miracle for example. There is no explanation for something like that happening. So you'd be forced to open up your mind a little bit and view possibilities you previously saw as impossible. That's all I think OP meant.
That's actually how I believe I ended up having the beliefs I have now. Over time I had and heard of a lot of what I would think to be unexplainable experiences, that made me look at things in ways I wouldn't otherwise. OP is hoping that if you do some of the things he mentioned, something similar would happen. Now I'm not trying to prove a point or anything, but it seemed like a lot of people didn't understand the original post at all, so I'm just trying to clear things up.
