Do you believe in God? Why/Why not?

Why not? When someone is placing god at the end of the equation it's because of ignorance. 

We don't know what caused the Big Bang
- I do, it was god. -> god of the gaps

We don't know how life started on this planet
- I do, it was god. -> god of the gaps

We don't know why there is more matter left in our universe. Matter and Anti-Matter should've all cancel each other out.
- I do, it was god. -> god of the gaps

 Using god of the gaps only for its original meaning / purpose would be a genetic fallacy. 

No, when people place God at the end because of ignorance, you have a God of the Gapps.

When you construct an argument that leads to this conclusion, it's obvious this doesn't apply.

But it doesn't, at least not by logic. 

What is the logical justification to jump from first cause to god. 

There are different depictions of the cosmological argument, which the simplest is this one: 

1) Everything that exists has a cause of its existence.
(2) The universe exists.
Therefore:
(3) The universe has a cause of its existence.
(4) If the universe has a cause of its existence, then that cause is God.
Therefore:
(5) God exists.  

How do you jump from 3 to 4? 

Even if this is just how the argument is being presented, I still don't get how they came to this conclusion. The only thing is being bias towards god's existence and being ignorant of any other options during it's creation. I know this argument has been already debunked and the criticism it gets is in my eyes also justified. But still.. how do you make such a jump?

I see it the same as that one from South Park: 

Stealing socks
???
Profit

And everyone is ok with it.
