Probably! And even potentially some orbiting the planet. They’d be part of the cosmic neutrino background, neutrinos around since the big bang which have had their velocity red-shifted to Newtonian speeds.
But they interact with things even less than relativistic neutrinos. Even a light-year of lead wouldn’t be enough to register a hit from one.
