Correct we can only 'see' back in time that is within a light cone. We can never know the infinite. We can only infer by what we see now.
As for the age of the Universe it is about 13.7 billion years.
Consider this and this is Olbers Paradox and mentioned by Edgar Allan Poe. If the Universe was truly infinite and was always there then the night sky would be as bright as any sun. No matter where you looked there would be a star! Why it is not is due to the finite speed of light and the fact that the Universe had a beginning.
Sorry this is the best I can do for now.
