Can someone tell me why it was decided that the pre big bang singularity was a speck smaller than a proton instead of maybe a speck the size of a pea or a baseball or a black hole?
​
That's what the word "singularity" means - a point of no dimension.
​
It wasn't "decided" to be that small, that's the size that the evidence suggests. When you look back in time, the universe gets smaller and smaller. Why would we expect that trend to stop at any size but the logical extreme - no size at all?
​
Also, am I correct in believing that the creator of this theory also believes that that speck contained all of the matter of this universe?
​
Before you make an argument from incredulity, why don't you tell us the total amount of matter in the universe? Remember, you have to count the anti-matter against the matter. How do you know that there's not zero net matter in the universe?

It seems that almost everyone I talk to believe that something and everything (matter and anti-matter) can be made from nothing.
​
Why do you suppose that is, exactly? Did you ever ask? I'm just curious.

Can someone tell me where this singularity was located
​
Obviously, it was located here.
​
Think about it for a minute.

It thins out timespace spacetime and allows for imagination driven relocation in annother galaxy.
​
And your basis for these assertions is what, exactly?

it was not located "here" as Crashfrog put it
​
No, it was located here. And there, too. You didn't think about my answer at all, did you?
​
Pretend you have a rewind-time machine. Go to an arbitrary point in the universe. Rewind time far enough and you'll discover you're at the location of the big bang.
​
Back in the present. Go to any other arbitrary point and repeat. You'll discover that you're at the location of the big bang.
​
Rinse and repeat. No matter where you go in the universe, if you go back in time far enough, you wind up at the exact location of the big bang without actually moving anywhere. This is because the big bang is the origin of all points in space.
​
When you say "where was the big bang?" what you're asking is "where is the universe?" Well, obviously, the universe is here.
