Question

1 are we alone? this question has weighed on the minds of humans for centuries. some have long claimed that alien life indeed exists both within earths solar system and beyond. still, conclusive proof of alien life has remained out of reach. recently, however, nasa scientists have given the world a reason to believe that the existence of alien life is not only possible, but probable. recent discoveries suggest that, beyond earth, the solar system is full of conditions that could support life as we know it. continuing evidence of water in other parts of the galaxy, as well as a recent breakthrough discovery of seven habitable exoplanets similar to earth, support the notion that finding alien life is a quickly approaching possibility. 2 scientists say that liquid water played a key role in the development of life select the two supporting claims that the author makes to argue that it is likely that alien exists beyond earth. findings of water on mars and europa have led to the discovery of past alien life. watery conditions elsewhere in the solar system support the possibility of alien life. planets with earth - like conditions may be common.

Explanation:

1. The first option is incorrect because the text states conclusive proof of alien life remains unreachable, and water findings only support the possibility, not confirm past alien life.
2. The second option matches the text's claim that the solar system has conditions (including water) that could support life.
3. The third option aligns with the discovery of seven Earth-like habitable exoplanets, implying such planets may be common and support alien life likelihood.

Answer:

• Watery conditions elsewhere in the solar system support the possibility of alien life.
• Planets with Earth-like conditions may be common.
