Disproving Odin - An Experiment in arguing with a theist with Theist logic

[SteveII]

1. Everything that begins to exist has a cause.
2. The universe began to exist.
3. Therefore, the universe has a cause.

Which number(s) do you think are false?

1.

The KCA fails at the first premise.

Name something that began to exist and tell us the exact moment this would have happened and the cause.

You might be able to manage it, I don't know. But for sure you can't say this about everything.

Item (cause)
Most of the elements/compounds that make up my keyboard began to exist (stars, pressure, other chemical reactions)
This post (me, electricity, my computer components, the internet and all the hardware necessary to maintain that connection)
I began to exist. (parents, biological processes)
My office began to exist (a builder, some supplies)
Our sun began to exist (dense gasses and whatnot)
Our galaxy began to exist (more of the same)

Now give me examples of things that don't have causes. 

Lest you think you can play around, let's use the same definition of the word:

cause
kôz/
noun

1. 1.
   a person or thing that gives rise to an action, phenomenon, or condition.
