After all, bees and ants and such have been on earth millions of years longer than we have and they haven't developed any non-organic technology. They aren't sending radio signals to the stars nor exploring the other bodies of our solar system.
Contrast that with humans: in less than 100,000 years we've gone from stone, bone, skin, fiber, and wood technology to nuclear. Not all intelligence is capable of letting the wider solar system know it's here.
I have a hunch that we will find life on other bodies in the solar system. But I'm afraid they'll be DNA based - which would almost certainly mean that the life is from Earth. It's already been shown that some microbes can survive for quite a long time in space. It only stands to reason that some microbes have been whisked out of our atmosphere via collisions. It doesn't take much energy to accelerate a bacterium to escape velocity.
