Question

Not So Lonely Planet

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
Earth's 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.
What is the author's main claim or argument?
Experts have claimed for years that alien life exists.
It is likely that alien life exists beyond Earth.
Scientists have discovered evidence of alien life.
