How can we get anti matteris there exist in a universe?
One has to go to far-away galaxies to get hold antimatter particles
Why is there not nearly as much antimatter than matter?
There are no definite answers with our current level of understanding of antimatter at this point but scientists believe that this is the result of an imbalance in the production of matter and antimatter particles in the early universe. Another explanation for this phenomenon is that Antimatter may exist in relatively large amounts in far away galaxies due to inflation in the primordial time of the universe

Why do you live in a universe that is made of matter rather than antimatter?
This is not currently known. There does exist some asymmetry between matter and antimatter - meaning that they are not exact opposites in all aspects - but this asymmetry is not enough to explain why matter exists.
