What technological methods do we currently have that can detect life on other planets?
Presently we're still trying to develop more sophisticated detection methods for terrestrial Earth-like exoplanets orbiting in the habitable zone surrounding its star. Even if we discover another world with the exact likeness, characteristics and chemical composition of our own planet (Earth's twin if you will) that still doesn't get us the proof we need to confirm living organisms on its surface via direct observation since extrasolar planets are obviously extremely faint light sources compared to their parent stars.
