Does the current SOTA believe that it's most likely that life originated on Earth? I know there are some theories that at least one of the critical building blocks was delivered via asteroid or other extra-terrestrial process.
But that doesn't answer the origin of life. Even if it came from outer space, it must have an origin somewhere. Currently, the science is focusing on the possibility that life originated here because the problem does not become easier to solve by considering another planet's environment.
