Final answer:
The most likely place to find life in the solar system beyond Earth is Mars, due to evidence of past habitable conditions and the potential for human habitat in the future. Europa, a moon of Jupiter, is also considered a possible location for microbial life.
Step-by-step explanation:
The most likely place in the solar system to find life other than Earth is Mars. This conclusion is based on our current understanding of the geological activity, evidence of habitable conditions in the planet's past, and the ongoing findings that suggest Mars could be a place for humans to inhabit in the future. Europa, a moon of Jupiter, is also a strong candidate due to the presence of a liquid ocean beneath its ice crust, where microbial life may exist.
However, the conditions on Venus are too harsh and Jupiter itself, being a gas giant with no solid surface, cannot support life as we know it. Mercury and the Moon are not considered because they are geologically inactive, leaving Mars as the best candidate among the given options.
