By 2040, will there be strong evidence of life originating on any moon, asteroid, or planet (other than Earth) in our solar system? This includes life that is non-cellular (e.g., a self-supporting virus), that is extinct (e.g. fossils), and that uses a genetic carrier other than RNA/DNA. Very strong chemical evidence -- for example, confirmed methane of biological origin on Enceladus -- may be sufficient to resolve this, but I will be skeptical of purely spectroscopic evidence.
