Question

Do aliens exist in reality ✌ Write a paragraph of 500 words on it :)​

Answer 1

Answer:

this moment, seven robotic spacecraft are roving or orbiting Mars, taking photos, gathering data, and generally doing the bidding of scientists back on Earth. After 15 years of this continuous robotic presence, we know the Red Planet better than any world besides our own. And planetary scientists have an answer, finally, to one of their oldest and most fundamental questions: Could Mars support life?

The answer is yes: certainly in the past, and very possibly today. In 2013, less than a year after Curiosity touched down in the ancient lakebed Gale Crater, John Grotzinger, the project’s principal investigator, announced with confidence: “We have found a habitable environment,” one where substantial amounts of surface water existed billions of years ago. What’s more, the Curiosity science team is convinced that the lakes and streams lasted for long periods, perhaps millions of years.Another announcement, just as momentous, followed last September: Water still flows on Mars today—at or very near the surface. For more than a decade, NASA’s strategy in exploring Mars has been to “follow the water”; the agency reasons that wherever there’s water, we might find life. Now, having made the case for water, space agencies are preparing to launch Mars missions whose primary purpose is to search for evidence of biology. And, unlike earlier searches, these missions have a real chance for success.

Answer 2

Answer:

no

Explanation:

We’ve all seen them: Scenes depicting chaos, panic, and hysteria following the detection of alien life. Buildings crumble, fires rage, riots break out, societies collapse. If that’s how Earthlings are going to deal with the news that there’s life beyond on Earth, why risk looking for it?

Well, maybe it won’t be so bad after all. When humans do find evidence of alien life, “we will take it rather well,” according to recent results presented today at the American Association for the Advancement of Scienceannual meeting in Austin, Texas.

“Of course, I would also predict that if a hostile armada showed up near Jupiter, we wouldn’t be happy,” study author Michael Varnum of Arizona State University said today during a press briefing at the AAAS meeting.

Looking at a mix of news headlines and survey responses, Varnum and his colleagues found that people’s reactions to detections of alien life, both hypothetically and to the famously false announcement of microbial fossils from Mars, are generally quite positive.

“To be honest, I wasn't at all sure what we would find,” Varnum tells...
