Hey there,
As a Christian, I'm a little confused at the the 'realization that God is fake'. Can you elaborate on your opinion? It's truly interesting!
A lot of the times, people go through troubling experiences and completely denote the existence of God based off of hardship (e.g. lost of loved one, death/incidents, wish not coming true, etc). While there are many answers to just about every problem we human beings are capable of having, what we feel and go through is just as important!
Pertaining to your question, though, that's another topic. I guess anyone can pick up a rock and call it god, but are we talking about looking for truth, or just what makes us feel better? That can be two different topics (and come on, usually it is!)
I think truth doesn't come easy to our ears, or definitely not to mine, because I'm usually 'set' in my ways. There are things I like to do and don't like to be told it's 'wrong' and feelings I like to feel that I don't care to change, etc. But then again, I think everyone may be like that at some point in their lives. Love the logic we alone build and call it truth - is it possible there's someone who knows more than us? Knows the best way to live? Knows truth? Yeah, looking for truth is a lot harder (again, I think it's because we make it hard!) then looking for something that makes us feel better. That's the easy part. Just look around in this world - media, idolizing celebs, etc. So many ways to just make us feel better, or as you said, 'pick your own god'.
I think if someone's going to pick something to idolize, hopefully that person understands..they just made it up! It's like believing a story that was clearly false. I believe Lord of the Rings was a true story! But if it makes me feel better, does it make it true?
Sorry to rant, I just think this branches off into another interesting topic - truth vs. self-gratification.
