Maybe not. It's highly unlikely, after all, that the cameras of our space probes will capture images of planetary surfaces covered with organisms, or the artifacts of intelligent life-forms. Chances are the evidence will be much more subtle: tantalizing spectral lines of biomolecules in the light from a distant earthlike world, or structures within rocks from another planet that are not of obvious geological (or even biological) origin."
