So newish news is that asteroids are not just rocks but lumps of ice. It is now the theory that we were a rock planet once, just lava and stuff until we were hit by an asteroid made mostly from water and this how life began here.
It's a fair comment though to say we are Aliens on this planet and if one such rock could hit us billions of years ago with DNA and all the other things that contain life, it will not be a coincidence in the cosmos as we got life on this planet from somewhere else so have many others out there.
Life could not have happened here if it did not come from somewhere else.
