What is your personal opinion about the existance of god, other than scriptures. just your personal reason.?

I personally believed humans have invented a God to explain the unknown and control the mes through fear and a reward system. That's what looking at religion has led me to believe so far. As for number four, if God is infinite, why can't the universe be? As for number five, of course everything seems so perfect because that's all we know. It still doesn't prove a creator. Why do we have stuff we pretty much don't need like a tail bone, wisdom teeth, toenails, males having , and more?
