4 th dimension is time , in mechanics it's inertia ( ie Inches to the 4 th power) . Science claims there are 9 to 12 dimensions, we live in them all.
Theory has a bad habit of using the same word too many times, dimension does not mean realities , of those there are an infinite number. It means dimensions as in L,D,H,Time etc.

because when we are born we know nothing if we had no history we would be animals we are still animals look at what we do how can this be highly intelligent it's not we have an history of accumulated intelligence
we have discovered a lot in other words in 10,000 years if we survive our descendants will know a lot more and we will be the cavemen for our naïve thoughts

It's about balance.

Eating is for staying alive i.e sustaining life when in balance and it becomes poison when not in balance.

Money similarly is balanced when we use it for buying necessaries and controlled pleasures, and it becomes our enemy when we use it for wrong things.

Happiness is also needed in balance i.e enough for us to want to stay alive, and not so much for us which would make us blind to pain of others, our purpose and Humanity.

Now God is also needed in balance, God is real but God would be real even after our death i.e when we go into spirit world so if God has send us here and not kept us in spirit world that means he want us to learn from this world, prove our worth, do good be fair and stuff. So only God is not recommended, do your best to attain your goal and pray afterwards, praying won't work in place of karma.

So balance would be the word for these 4 things and you name more, balance would be requirement for them too. So life is about Balance.

You misunderstand the basic premis of your statement. You are not at the "center" of the universe wherever you go. (as if you could go anywhere much other than the immediate area of the earth). It's just as the other answer says, the universe looks pretty much the same in all directions until you get down to the finer details.
No....Yet again.... We do not create reality with our minds.

I do find this tedious and I do tire of writing it out.... The universe is 14 billion years old.

For billions of years, there was nothing in all the universe but diffuse clouds of mostly-hydrogen and huge flaming masses of hydrogen...First-generation stars. Those stars had to go through their primary cycle and "cook" the more complex elements in their cores, then blast them out into void when they went nova.
To reform into more-complex systems with complex, rocky planets that could harbor life.
And then MORE billions before that life could become complex enough to ask silly questions.
