Maybe similar with 'outlander' movie
There are so many things that could not be a falsifiable hypothesis. One statement that is not falsifiable is that humans need air to breathe.
At the moment there is no credible evidence that there are any extraterrestrials on earth.
It can be true, but there is no proof. I found it interesting when such an idea was brought up in "Ancient Aliens" on the History channel.
Not extraterrestrial ones. Though an alien is also someone living in a country that was not born there and is not a naturalised citizen.
Sorry. Despite what you see in Hollywood, there has been no confirmed encounter with extraterrestrial life on earth.
Extraterrestrial are unknown humans. They are humans, but different kinds from different planets. Like aliens and UFOs. The scientific community think this is true. They think they come from planets beyond Earth...
They have studied and researched our solar system and found no extraterrestrial life beyond the Earth.
Extraterrestrial life is defined as life that does not originate from Earth. Life on other planets is a simpler way to word it. Aliens on other planets is an example (but I doubt aliens live on other planets) of extraterrestrial life. Also, bacteria are another example. There is proof that there was once water on Mars, and that there may have been bacteria living in that water. That bacteria would also be considered as extraterrestrial.
He knows as much as the rest of us; there is no credible evidence that any extraterrestrial intelligence has ever visited planet Earth. However, he very easily concedes the very real potential for the existence of extraterrestrial life.
Extraterrestrial is an adjective, meaning not of this Earth.
Extraterrestrial rock is rock that did not originate from Earth.
If there are any they would not be from EarthAns 2.There are lots of aliens and they are from Earth. Anyone you meet in your country who is not a citizen of your country is an alien. By definition - look in any dictionary.UFOlogists would find fewer people laughing at them if they learned the word extraterrestrial.
