Quasars -- celestial objects so far away that their light takes at least 500 million years to reach Earth -- have been seen since 1963  For anything that far away to appear from Earth the way quasars do, it would have to burn steadily at a rate that produces more light than 90 billion suns would produce
But nothing that burns at a rate that produces that much light could exist for more than about 100 million years
Nothing that is as far from Earth as quasars are can continue to exist for more than about 100 million years.
