For the same reason that it's quite possible to get a letter in the mail today from
an old friend who passed away last week.
It takes light time to travel from the star to you. From the sun, it only takes
8 minutes, but from the next nearest star, it takes 4 years, and you can see
at least one object in the sky with your naked eyes whose light took over
2 million years to get here.
That light is what you're seeing. Nobody has any idea what might have happened
to that object since then, or whether it even still exists.
