Your question is a bit vague, but I believe you are asking why is Beowulf, the tale, important to modern society. It is important for several reasons. First, it gives modern man insights into what was important to earlier humans; what mattered to them, what constituted a hero. We can see from this tale that many of the same things that were important then, are still important to this day. Secondly, it is important as a historical document due to its advanced age.
