6. Because they haven't sent us signals?

If they're smart, they probably don't want such a violent species to know of their existence. Or we don't happen to have turned a radio telescope their way.

But... a brown dwarf? How long can it stay hot enough? A red dwarf has a nuclear furnace, and can burn many times longer than our own hotter star. But a brown dwarf will eventually radiate away its heat of creation. And it takes billions of years to evolve advanced life... Worth further investigation though!!

On edit: the article below lays out a case for brown dwarf planets that could exist in the (continually cooling) habitable zone of a Brown Dwarf for 0.1 to 10 billion years. That's potentially enough time for advanced life to evolve!
