My opinion is probably the most neutral one in this topic.
Let us start with an example from politics.
What is politics?
Humans arguing what is wrong and what is right.
Why do politics change?
Humans change their mind on what is wrong and what is right.
What can we conclude from this?
There is no right or wrong.
If the amount of people(1st group) supporting one idea exceeds the amount of people(2nd group) saying the idea is wrong, the 1st group becomes automatically "right". (democratic example).
There are tons and tons of opinions, there is no way to say who is right or wrong.
And by that logic, the chances of that god exists are exactly the same as the chances that god does not.
We don't know it. How could we, we are just humans.
Although, religion is somewhat else.
I watched the video that King125 posted before and there it mentioned that there have been thousands of religions in world.
So what are the chances that muslims got it right? the jews got it right? the ancient Estonians got it right?
Maybe there is god somewhere. He could be on Earth. He could be behind a PS2 controller controlling the world.
So what are the chances that some religion in the world got it right, exactly right - who is the god, where is the god, where is the heaven, is there even a heaven? or second life? how can you get there? how does god act? etc, etc, etc.
Exactly the same as there is a god no one has discovered or knows about, we are not aware of him at all, we don't know how he acts, we don't know what we should do to get his attention, do we even get his attention? is he human? maybe he is the whole earth (as ancient Estonians believed that everything has a soul)?
And, Drugs really did give a perfect example. All of the religions have been made up by someone. Anyone could make a religion this moment and you couldn't tell him that he is not right. Maybe Drugs is god.
There simply is no right or wrong in this debate,
Thank you.
TL;DR: WHAT ARE THE CHANCES THAT DRUGS IS GOD? EXACTLY THE SAME AS GOD IS NOT REAL, JEWS GOT IT RIGHT, MUSLIMS GOT IT RIGHT, ANY RELIGION IN THE WORLD GOT IT RIGHT.
