Has the universe always been in existence?

I was doing deep philosophical thinking (really? Who woulda guessed?) and I was trying to explain time to someone.

Sort of.  

I was saying the reason that people created the idea of a god is because they think that there needs to be a reason for the creation of earth and man.   

The reason that people think there needs to be a reason for the creation of earth and man is because humans are born and then they die. I don't think of the human species as being infinite, I suppose I trust the theory of evolution for explaining humans, but I also know that we could go extinct, just like any other animal on earth. 

 People created a god out of their minds that "Created" earth and some believe that someday there will be a rapture and the earth will end. This is how some religions have justified the creation of humans and earth.   

There are so many myths and creation stories about how the earth and how us as humans were created. But they need to remain as myths.  

Humans most likely evolved from other species over billions of years. Earth may not have always existed but the universe must have to have existed. To be something, there must have always been something. I hold the understanding that the universe is infinite.  

As humans, since we can't grasp the concept of not having a beginning (since all things in our lives have a beginning) we have a hard time grasping the idea that things have just always existed. Maybe not the human race, or earth. But the universe has. This is my theory. It makes sense to me.  

For something to exist, something must've always existed.  

But I guess to a certain degree, the creation of earth probably had to do with something like the big bang or something scientific I honestly couldn't explain to you since my major isn't physics.   

My overall point here is that the universe has probably always existed. Something cannot come from nothing. So something must've existed, whether it is darkness or light. Something existed. Little atoms, particles, have existed. I think the earth and humans have somehow come from this something.   

But there has to have always been something, nevertheless. We can't create something out of nothing. 

Why did man create god?

I am briefly straying from my 30 day writing challenge. I will do the 21st-23rd, tomorrow. 

I need to talk about something that has been on my mind (again).

That would be religion.

Or, rather, theism, as I have established before that religion is just a societal group, that happens to share an identical view on god. 

I am very interested in why people believe in god. There are so many reasons that are simple and some more complex: 

- That is what people were taught and they choose to believe it

- Don't want to be outcasts from society/ just following social norms

- It seems logical to them somehow

- They are optimistic about heaven or believe it exists so they believe in god just in case it does exist

More complex ideas I've talked about before are like

- People use the concept of god to rid themselves about what they feel bad about doing (sort of like apologizing without actually apologizing to the person you've hurt)

- People are drawn to the concept because they like this idea of hope, after a hard time in their life

- people think society will fall apart and act immorally without religion 

People don't just believe in god. There is a reason. Even like the statement "people don't just believe in iPads". Either they believe in them because they have one, have seen one, are gullible, and they trust their senses to be honest to their minds. 

Someone who says "I just believe in god because he exists" has to have a reason. Whether it was the way they were raised, they are getting false hope psychologically... Who knows.

Today I've furthered my thinking... Beyond "why do people believe in god?" I wonder "why and when did people create god?"

Obviously a high percentage of people are theists, for reasons I have just discussed... But I want to know why and when people created this idea of a superior being.

I read an article about a study ill link to here later if I remember, about how people are always dependent on another, so creating a god can relieve this need of dependency on something.

I want to know the first mind who thought up the idea of a god.

I've always imagined it to be some authority figure like a king or something, who gained his authority by lying and saying a man, the creator, is speaking to him, and therefore this man and now king may rule. There is no proof of that, I just think that could be a theory. It would make a goods historical-fiction novel, actually.

I don't know. I'm going to keep on pondering.

Why do you think man created god?
