It is possible to ask questions which make no sense or have no answer. The way the human mind works tends to revolve around things having a beginning or an end. We start life, we end life. Structures are created and detroyed.

However, that's not how things work in the universe. Things do not become created or destroyed, and nobody has ever observed the creation of matter or energy outside of equal-and-opposite situations where you create antimatter and matter at the same time.

We live in a universe where "creation" isn't a thing, and it may be well that the question of "when did the universe begin" is as odd and strange as asking "where is the top of a circle" or "what is north of the north pole"

What about Entropy? if the universe has been around literally forever, shouldn't there have been a heat-death of the universe by now?

Not having a beginning does not necessarily imply that the universe has existed forever at any single point, AFAIK. Also the universe could be in a "cycle" where it starts and restarts, but without having a beginning or and end.
