Sadly, no, it is impossible mathematically, even with billions of planets potentially able to withstand life, everything has to be perfect, and even then the spark of life has a trillions and trillions to one shot of occurring. Any alien sightings are an overactive imagination, that is why there is literally no physical evidence ever presented.
It is possible for aliens to exist but there is no evidence showing that aliens are, in fact, real or of any existence. There are claims of alien sighting and UFOs but there is no proof. So, it is presently based on what the people believe! Hope this helps :)
It would be extremely foolish to say no. The universe is ever expanding and that non exists is simply foolhardy. It doesnt have to be intelligent life, mind you. Bacteria and microbes and other one celled things count.
Water has been found on mars. Here on earth, water pretty much equals life. This may be the same on mars. It is very exciting because the water on mars is flowing and not frozen. Mars expeditions are now heavily focused on finding any life on mars.
Yes . In our sun 8 planets go around the sun. There are trillion stars in our galaxy , with each start more than 1 planet go around the start . means there are trillions ,trillions planets are . there are a thousand aliens but maybe some smart and some like animals like here . But they are different because my form came because of gravity and the weather here in earth .
I believe that in fact there is but not in this solar system scientist have found a plant that they named 'G187' in a distant solar system the planet is similar; plants, land, and water. But no aliens that can come in contact with us unless they are a highly advanced race.
from the research till now it can be possible that grey aliens do exists there are many cases that people have seen ufos in the sky also there are cases that people have seen aliens in different parts of the world and there are sketches given by these people and guess what , those sketches are almost same that is big head , long arms . big eyes etc also it can be possible that these aliens are no one but our future humans who travel back in time because as time will go on human body will change and it can be possible that we humans will look like grey aliens after millions of years from now
